Rahim Kanji	38841bf189	Remove DESCRIBE statement cache option ... Remove the `DESCRIBE` (statement) cache option and related cache code.	8 months ago
Rahim Kanji	9a5fa148c8	Inject implicit Sync if simple query arrives before extended query cycle is completed ... When a simple query arrives while extended query messages are pending, we now: - inject an implicit Sync, - process all extended query messages, - then execute the simple query, - and send ReadyForQuery only after the simple query completes.	8 months ago
Rahim Kanji	be2ae45950	Merge branch 'v3.0' into 'v3.0_extended_query_protocol_phase_2'	8 months ago
Rahim Kanji	abd19113c0	Fix RequestEnd: avoid updating internal state when query failed on backend ... RequestEnd was applying state changes (session variable restore, rollback-to-savepoint, multiplexing toggle for temp tables/sequences) even when the query failed to execute on the backend connection. This caused internal state to diverge from the actual backend state. Fix: - Add success/failure flag to RequestEnd calls. - Restrict state-changing logic to Simple Query and Prepared Execute. - Ensure logic only runs when the query executed successfully on backend. This keeps internal state aligned with the backend connection state.	8 months ago

Rahim Kanji	7a1852fb92	Skip Describe Portal results unless client explicitly requests it ... PQsendQueryPrepared always emits Bind -> Describe Portal -> Execute, which led to RowDescription being included in the result set even when the client never sent a Describe message. This caused clients to receive row descriptions they did not request. Changes: - Skip including RowDescription when the client did not send Describe. - If the client explicitly sent Describe followed by Execute, continue to skip redundant execution of Describe but include RowDescription once. This ensures RowDescription is only sent when requested, aligning behavior with protocol expectations.	8 months ago
Rahim Kanji	3dd401f81a	Queue client packets during active query execution ... Previously, any packet received while a query was still running was considered unexpected, and the session was terminated. This often occurred with pgJDBC, which pipelines commands (e.g., sending `BEGIN` immediately followed by another statement). Now, new packets are placed in a FIFO queue and processed only after the current query finishes and its response is sent. This preserves correct ordering, prevents unnecessary session termination, and improves compatibility with connectors like pgJDBC.	8 months ago
Rahim Kanji	fff2a91381	Fix omission of ReadyForQuery after error with pending extended-query messages ... In extended query mode, ReadyForQuery is normally deferred when there are pending messages in the queue; it is sent only after the entire extended query frame has been processed. Edge case: if a message fails with an error while the queue still contains pending messages, the queue is cleared later in the session and those pending messages are discarded. In that case, ReadyForQuery would never be sent. Change: when a result indicates an error, send ReadyForQuery immediately. The extended-query flag will still be reset later in the session. This ensures ReadyForQuery is always emitted and prevents clients from waiting indefinitely.	8 months ago
Rahim Kanji	8a3bab5002	Ensure consistent handling of NoData packets in PQsendQueryPrepared ... The PQsendQueryPrepared function transmits the sequence BIND -> DESCRIBE(PORTAL) -> EXECUTE -> SYNC. However, libpq does not indicate whether the DESCRIBE PORTAL step produces a NoData packet for commands such as INSERT, DELETE, or UPDATE. In these cases, libpq returns PGRES_COMMAND_OK, whereas SELECT statements yield PGRES_SINGLE_TUPLE or PGRES_TUPLES_OK. This update explicitly appends a NoData packet to the result in order to provide consistent behavior across query types.	8 months ago
