I installed and started PostgreSQL and it worked fine for days. Then I restarted my computer and now I can't start PostgreSQL ('pg_ctl -D pgdata -l pgdata/psql.log start'). Here's what's in my log: LOG: received immediate shutdown request WARNING: terminating connection because of crash of another server process DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory. HINT: In a moment you should be able to reconnect to the database and repeat your command. FATAL: database files are incompatible with server DETAIL: The database cluster was initialized without HAVE_INT64_TIMESTAMP but the server was compiled with HAVE_INT64_TIMESTAMP. HINT: It looks like you need to recompile or initdb. I guess my computer restart didn't agree with PostgreSQL. But I've had crashes before and never had a problem getting PostgreSQL going again. Anybody know how to fix this? I also tried 'pg_resetxlog -f pgdata' but still get the same error trying to start up. Thanks, csn Mac OS 10.4.7 PostgreSQL 8.1.3 __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
