On this issue, instead of going for a newer version of xlc, as suggested, I opted to get a newer version of the Postgres source code, 9.1.4. After compiling it with the same xlc version, I found that pg_dump works as expected. So, the problem appears to be somewhere in the 9.1 source code, at least for binaries created from it for AIX (6.1). Regards. Alanoly. -----Original Message----- From: Tom Lane [mailto:tgl@xxxxxxxxxxxxx] Sent: Friday, July 27, 2012 12:13 PM To: Alanoly Andrews Cc: 'pgsql-admin@xxxxxxxxxxxxxx' Subject: Re: pg_dump on Postgres 9.1 Alanoly Andrews <alanolya@xxxxxxxxxx> writes: > Is there any reported bug with pg_dump in Postgres 9.1, on AIX ? The following command hangs for "ever" and has to be interrupted. It creates a zero-length file. We had a recent report of strange server-side behavior on AIX that went away after rebuilding with a newer version of xlc, suggesting that the code was getting bitten by an xlc optimization bug. Perhaps this is the same thing inside pg_dump. If you're not using the latest xlc, try updating. If you are, does rebuilding with -O0 change the behavior? regards, tom lane **************************************************** This e-mail may be privileged and/or confidential, and the sender does not waive any related rights and obligations.
