Dear Friends,

I was looking for a structure like oracle or ms Sql server in Postgres. What I have expected is individual datafiles for individual databases. But i cant fine such items in the /usr/local/pgsql/data directory.

Will the postgres create individual data file for databases?

How to get the datafile path of a database?

Please shed light.

Regards
Kumar

Yes.

/var/lib/pgsql/data/base/, database directory name = pg_database.oid. You
can also use oid2name contrib module for finer detail.

No.  Just as with Oracle, PostgreSQL creates multiple files for each
database.

select oid, datname from pg_database;

The path for database 'datname' will be:
   $PGDATA/base/oid/

"aa454","@","freenet.carleton.ca"

People can be set wondering by loading obscure personal patchable
systems, and sending bug reports.  Who would not stop and wonder upon
seeing "Experimental TD80-TAPE 1.17, MegaDeath 2.5..."?  The same for
provocatively-named functions and variables in stack traces.
