Can someone enlighten me to how postgres handles disk writing? I've read some generic remarks about buffers, but that's about it. We have a chunk of code that calls Postgres in a less-than-optimal way within a transaction block. I'm wondering where to prioritize fixing it, as the traffic on the wire isn't an issue. Basically the code looks like this: begin; update foo set foo.a='1' where foo.bar = 1; ... update foo set foo.b='2' where foo.bar = 1; ... update foo set foo.c='3' where foo.bar = 1; commit; If the updates are likely to be a memory based operation, consolidating them can wait. If they are likely to hit the disk, I should schedule refactoring this code sooner than later. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
