Then how could i make it (SCHEMA)..??
There are many tables split on 4 databases on my previous
databases (MS-SQL Server). Could you give me more
explanations about PostgreSQL-Schema. I've tried to search
about schema on many url but i still don't clearly understand
about "schema", there's no Create Schema command or
some command that's following with option schema. In the middle of
my confusing i tried to using command "create schema my_schema;"
it wasn't error show up, but my_schema that's i created is the same
with other database and it could dropped using "drop database my_schema".
So do you have any idea how to make a schema on PostgreSQL..??? and
anybody have any examples that's using "contrib/dblink"...???.
Sorry for very-basicly question.
Some Advices will be helpfull.
TIA and GOD Bless You.
