The AI documentation covers how to configure each provider in some detail, but it says nothing about what actually leaves the server once one is configured, which is the first thing anyone working under data residency requirements, procurement policy or sector-specific rules is going to want to know. This adds a provider-neutral Data Handling and Provider Selection section to ai_tools.rst to close that gap, and cross-references it from the AI Assistant notes in the Query Tool documentation.

The section covers three things: what may be transmitted, when nothing is transmitted, and whose terms apply.

On the first, I verified each claim against the code rather than describing what I assumed it did, so it names schema definitions, server and database configuration settings read from pg_settings (llm/reports/queries.py), query text, EXPLAIN plan output (llm/prompts/explain.py), and row data via the Query Tool assistant's execute_sql_query tool, which is worth mentioning explicitly because people reasonably assume only metadata is sent. That tool runs inside a read-only transaction and caps results at 1000 rows (llm/tools/database.py), and saying so bounds the exposure rather than leaving the reader to imagine the worst.

On the second, note that the accurate statement is that no provider is configured by default: LLM_ENABLED itself defaults to True (config.py), whilst DEFAULT_LLM_PROVIDER is empty, so it is the absent provider rather than a disabled master switch that means nothing is sent out of the box. Locally hosted providers such as Ollama and Docker Model Runner transmit nothing externally either.

On the third, I have deliberately kept the wording generic, pointing the reader at data residency requirements, procurement policies and sector-specific rules, and at the provider's own terms and their organisation's policies, without naming any particular jurisdiction or restriction. Anything more specific dates badly, is inevitably parochial in a document read worldwide, and commits us to maintaining a footnote that earns nothing: a reader affected by such a rule already knows to go and check it, and the generic phrasing tells them to. The closing sentence makes explicit that the provider list reflects the APIs pgAdmin is able to speak to rather than a recommendation.

make docs builds clean, with the only warning being the pre-existing missing code_snippets reference in contributions.rst. The new section renders as a sibling of Configuring AI Reports and Security Reports, and the :ref: from query_tool.rst resolves.

Documentation only, so no release notes entry, in line with our deferred changelog practice. I have written this one myself, so it wants review from another committer rather than me.

Summary by CodeRabbit

  • Documentation
    • Added information about data shared with configured cloud AI providers, including query context and potential read-only result data.
    • Clarified when data is not transmitted and noted provider terminology, jurisdiction considerations, and default provider settings.
    • Documented that AI-generated queries may include DDL statements.
    • Added a link to the AI data-handling guidance from the query tool documentation.

The AI documentation covered how to configure each provider but said
nothing about what actually leaves the server once one is configured,
which is the first question anyone working under data residency or
procurement constraints will ask.

This adds a provider-neutral section to the AI Reports documentation
setting out what may be transmitted, which is schema definitions,
configuration settings read from pg_settings, query text, EXPLAIN plan
output and, because the Query Tool assistant can run read-only queries,
row data where the assistant judges it necessary; when nothing is
transmitted at all, which is the default, since no provider is
configured out of the box; and the fact that each provider processes
that data under its own terms and in locations of its own choosing, so
the reader knows to check both those terms and their own organisation's
policies before enabling a cloud provider.

It also makes explicit that the list of providers reflects the APIs
pgAdmin can speak to rather than a recommendation, and cross-references
the new section from the AI Assistant notes in the Query Tool
documentation.

Review Change Stack

Walkthrough

The documentation adds AI data-handling details for cloud LLM providers. It also states that generated AI Assistant queries can include DDL statements and links to the data-handling information.

Layer / File(s) Summary
Data handling and query guidance
docs/en_US/ai_tools.rst, docs/en_US/query_tool.rst
The documentation describes transmitted metadata, settings, query text, EXPLAIN output, and possible row data. It documents conditions that prevent transmission, provider jurisdiction considerations, and the non-recommendatory provider list. It also documents DDL support and links to the data-handling section.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 9fb46

The documentation adds useful guidance about AI data handling, but its current wording could lead users to believe that locally hosted providers receive no data at all, which may misinform privacy and data-residency decisions. It also needs minor clarification about read-only execution and the per-call result limit, so the PR should be updated before merge.

Query Tool is also able to run queries against your database, within a read-only
transaction and limited to 1000 rows, so row data may be included where the
assistant determines it is needed to answer a question.

Define the 1000-row limit as per query call.

execute_sql_query truncates each returned result to 1000 rows. Multiple tool calls can therefore return more than 1000 rows in one conversation. State that the limit applies to each query call, not the full conversation.

Clarify transmission to local providers.

Lines 99-103 say that none of the data is transmitted when Ollama or Docker Model Runner is configured. Those providers still receive the prompt and database context through their APIs. The correct distinction is that data is sent to the local provider instead of an external cloud provider.

Proposed wording
- None of this is transmitted unless you invoke an AI feature, and none of it is
- transmitted at all when no provider has been configured, which is the default;
- when AI features have been disabled by the administrator through the
- ``LLM_ENABLED`` setting; or when a locally hosted provider such as Ollama or
- Docker Model Runner is configured.
+ This data is sent to an LLM provider only when you invoke an AI feature. No
+ data is sent to an LLM provider when no provider has been configured, which is
+ the default, or when AI features have been disabled by the administrator
+ through the ``LLM_ENABLED`` setting. When a locally hosted provider such as
+ Ollama or Docker Model Runner is configured, pgAdmin sends the data to that
+ local provider instead of an external cloud provider.

Describe write and DDL support as generation.

The AI Assistant database tool is read-only: web/pgadmin/llm/tools/database.py:849-907 routes execute_sql_query to execute_readonly_query, and web/pgadmin/llm/tools/database.py:116-184 sets the connection to read-only. Replace “supports” with “can generate” so users do not expect the assistant to execute INSERT, UPDATE, DELETE, or DDL statements directly.

Proposed wording
- your database structure. It supports SELECT, INSERT, UPDATE, DELETE, and DDL
- statements. All generated queries should be reviewed before execution. See
