and FreeDir routines modeled on the existing AllocateFile/FreeFile. Like the latter, these routines will avoid failing on EMFILE/ENFILE conditions whenever possible, and will prevent leakage of directory descriptors if an elog() occurs while one is open. Also, reduce PANIC to ERROR in MoveOfflineLogs() --- this is not critical code and there is no reason to force a DB restart on failure. All per recent trouble report from Olivier Hubaut.
This module contains two functions that report the size of a given
database or relation. E.g.,
SELECT database_size('template1');
SELECT relation_size('pg_class');
These functions report the actual file system space. Thus, users can
avoid digging through the details of the database directories.
Copy this directory to contrib/dbsize in your PostgreSQL source tree.
Then just run make; make install. Finally, load the functions into any
database using dbsize.sql.
When computing the size of a table, it does not include TOAST or index
disk space.
