Hello,
I've found in our server ( PostgreSQL 13.5 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44), 64-bit ) following error:
2022-03-31 09:29:58 CEST [15490]: [1-1] user=app,db=main,host=192.168.1.231,app=[unknown] ERROR: could not access status of transaction 3021015672
2022-03-31 09:29:58 CEST [15490]: [2-1] user=app,db=main,host=192.168.1.231,app=[unknown] DETAIL: Could not open file "pg_xact/0B41": Adresář nebo soubor neexistuje.
2022-03-31 09:29:58 CEST [15490]: [3-1] user=app,db=main,host=192.168.1.231,app=[unknown] STATEMENT: LISTEN "CONFIG"
Since we have enabled track_commit_timestamp, I' tried:
prematch=# show track_commit_timestamp ;
track_commit_timestamp
------------------------
on
(1 row)
prematch=# select * from pg_xact_commit_timestamp('3021015672');
pg_xact_commit_timestamp
--------------------------
(1 row)
Since this was not helpful, searching in the archives, I've found the thread:
"BUG #16961: Could not access status of transaction"
But it looks not to have any result.
Unfortunately, I have no isolated test case, so I'd like to ask for advice on what set of information to collect if it happened next time, to be able to supply some valuable bug reports.
If it is a known configuration issue or an application logic issue, any advice is welcome (the scenario described in the abovementioned thread is not our application case).
Thanks, Ales
