Hi, I'm trying to upgrade our database server from postgresql 32-bit 8.2.4 running on Windows Server 2008 to postgresql 64-bit 9.2.4 on ubuntu server 12.04.02 LTS. I have dumped one of our databases from our windows server and restored it on the postgres server running on ubuntu in order to test for incompatibilities. But the thing I am noticing playing with pgAdmin is that queries are being performed much more slowly on the linux server compared to the old windows 2k8 server, even with linux running on a ssd with more ram, faster cpu etc. I've tried running ANALYZE, VACUUM and combinations of these via pgAdmin on the linux database but performing queries consistently take 10x the amount of time that they take on the windows server so I'm obviously missing something here. The dump is a simple pg_dump -F c -f data.backup, then using pg_restore to restore in an empty database created with template0. What could be causing the new database to perform so abysmal?
