DD is used for development, and DP in production. After develop something on DD, a diff package is made and it upgrades DP. Normally after that DD has to be identically with DP. The problem is when I check the structure difference between DD and DP. My procedure is to use pg_dump to make a plain text dump of the two databases, and compare them, ignoring the comments. All the procedures are sorted identically, excepting those with the same name, but different arguments. Do you know a method to get the same text dump ? TIA, Sabin ^ permalink raw reply [nested|flat] 3+ messages in thread

Yeah, this has been complained about before. The problem is that pg_dump's DOTypeNameCompare() function sorts only by object name, and if the names are the same then by object OID (which typically boils down to being the creation order). Ideally we should get it to consider more data, such as the argument lists for similarly-named functions, before falling back on OID order. If you're not up to hacking a fix for that, you could try dropping the functions and re-creating them in the same order on both machines, so that the OID sort produces similar results. regards, tom lane ^ permalink raw reply [nested|flat] 3+ messages in thread

Depending on what kind of objects you want to check this may be a - very ugly and complicate - solution. In my case I was only interested in the object definition, not the data. here my old code for the procs.... select 'pg_proc' ||'|'|| proowner ||'|'|| proname ||'|'|| prolang ||'|'|| case when proisagg =true then 'y' else 'n' end ||'|'|| case when prosecdef =true then 'y' else 'n' end ||'|'|| case when proisstrict =true then 'y' else 'n' end ||'|'|| case when proretset =true then 'y' else 'n' end ||'|'|| provolatile ||'|'|| pronargs ||'|'|| prorettype ||'|'|| to_querystring(proargtypes) ||'|'|| to_querystring(proargmodes) ||'|'|| to_querystring(proargnames) ||'|' AS CHECKSTRING from pg_proc order by CHECKSTRING Marc Mamin -----Original Message----- From: pgsql-admin-owner@postgresql.org [mailto:pgsql-admin-owner@postgresql.org] On Behalf Of Sabin Coanda Sent: Thursday, March 26, 2009 3:54 PM To: pgsql-admin@postgresql.org Subject: [ADMIN] plain text difference with pg_dump Hi there, I have two databases DD and DP.
