I would like to know how Postgresql works when all the files (checkpoint_segment *2 + 1)

does Postgresql rollback the transaction when all the wal segments are used,
or does the server stop with an error message ?
(I have tried to make the test but without success for finding a long transaction)

AIUI it just keeps creating more segments. i.e. checkpoint_segment is
not a hard limit. It's just the number it keeps around and recycles
rather than continually creating and deleteing files.

Have a nice day,
Thanks for the answer, that's clarify how it's work
I ask this question about  'long transaction' (between two commits)
because it was a problem on old release of IDS Informix.
Please, what is the meaning of  'AIUI' ......
Thanks
