Rahim Kanji	205f970ffa	Append NoData for DESCRIBE(Portal) on SET/RESET/DISCARD/DEALLOCATE	6 months ago
Rahim Kanji	031d362aab	Add STMT prefix to ASYC DESCRIBE status	6 months ago
Rahim Kanji	7d5fe54230	Refactor: unify result handling for Parse and Describe ... Previously, Parse and Describe each had their own query result handling paths. This duplicated a lot of logic and also failed to handle some cases correctly—for example, Notice messages returned by the server during extended-protocol queries. Keeping these separate paths would be hard to maintain and prone to bugs. The simple-query result handling is already mature, optimized, and covers all the necessary cases. Reusing it for Parse and Describe makes behavior consistent across simple and extended query flows, while also reducing duplicate code.	6 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.	6 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.	6 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.	6 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.	6 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.	6 months ago
