Re: Postgre 7.3.2 pg_clog error

I just observed a very similar problem with Postgres 7.2.1 on Linux.
It happened while running transaction which inserts a large number of
records.

From the log-file:
... ...
2003-03-19 17:00:18 DEBUG: recycled transaction log file 0000000000000000
2003-03-19 17:09:56 DEBUG: XLogWrite: new log file created - consider
increasing WAL_FILES
2003-03-19 17:10:22 DEBUG: recycled transaction log file 0000000000000001
2003-03-19 17:15:25 DEBUG: recycled transaction log file 0000000000000002
2003-03-19 17:23:40 DEBUG: XLogWrite: new log file created - consider
increasing WAL_FILES
... ...
Rao, what platform you're running on?
