[SQL] Datafiles for Databases

[Kumar]

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
