I’ve got two PostgreSQL databases that have been created using the same sql file. One of them is 2GB larger. Can someone help me figure out why? I’m sure the databases have the same row counts, tables, indexes, etc.. The databases are on different servers, there are small differences in the postgresql.conf and the PostgreSQL version. Would something there change size on disk?
You mentioned they are on two different servers and two different versions. Is it possible you have a 32-bit OS and a 64-bit OS differences, or major version changes (because we don’t know all the changes that the Postgresql team has made to the underlying data structures on disk). You may find it has something to do with internal formats of indexes that are optimized for a particular machine’s OS/CPU features, etc.
My comments are purely speculation, I have no data to back up my ‘claims’.
