Zdenek Kotala napsal(a):
I though more about it and I discussed it with Radek yesterday. The
problem is that collation must be created before user want to use CREATE
DATABASE ... COLLATE ... command. It inclines to have have pg_collation
as a global catalog, but ANSI specifies to use schema name in collation
specification and schemes are database specific ... It means that
pg_collation have to be non-shared catalog and new database only
inherits collation from template db. And CREATE DATABASE have to check
list of collation in template database :(.
thinking more ...
It must be shared catalog because pg_database will depend on it.
