Hi all, just a very quick question: Does OID of each data type stays the same in any installation of PostgreSql and when database is used e.g. OID for data type "bool" is 16, "char" is 18 etc. Or is the case that this identifiers can change?
Thanks!

I'm worried that the reason that you're asking is because you wish to use the oids elsewhere. Don't rely on oids. Those are for internal use only. Have a look at pg_type for information on data types.
Why exactly are you asking? What are you trying to do?
