I am using postgres v.14 on rhel8 I enabled the track_commit_timestamp parameter.
postgres [379418]=# show track_commit_timestamp ; ┌────────────────────────┐ │ track_commit_timestamp │ ├────────────────────────┤ │ on │ └────────────────────────┘ (1 row) I performed a recover with the_recovery_target_time parameter. In the postgres log the following informations are present: statement: alter system set recovery_target_time = '2023-05-15 16:10:00' recovery stopping before commit of transaction 53013547, time 2023-05-15 16:10:00.150823+02 I would like to get the xid related timestamp with the following query: postgres[379418]=#select pg_xact_commit_timestamp(53013547); ERROR: function pg_xact_commit_timestamp(integer) does not exist LINE 1: select pg_xact_commit_timestamp(53013547); ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. What is the xid type and how can I cast integer value to make pg_xact_commit_timestamp to work? Regards Fabrice Chapuis
