Обсуждение: Where is the logig to create a table file?

When I use 'create table t(a int);'; suppose that this table t's oid is 1200,
then postgres will create a file named 1200 in the $PGDATA/base, So where
is the logic code in the internal?

Or if you are searching for the logic to determin the file name, see
GetNewRelFileNumber().
