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?
