Is pg_test_fsync contrib module in postgresql 9.2 deprecated?

Question

I have installed postgresql 9.2.4 on my machine with Ubuntu 12.04.1 LTS. Based on this documentation page (http://www.postgresql.org/docs/9.2/static/pgtestfsync.html), it seems *pg_test_fsync* contrib module is part of postgresql 9.2.4 . But when I checked *pg_available_extensions* system view and also the following location on my system /usr/share/postgresql/9.2/extension, I could not find this module. It seems to be missing even in the contrib documentation here (http://packages.debian.org/experimental/postgresql-contrib-9.2).

Am I missing something? Could anyone guide me on how can I test 'pg_test_fsync' on postgresql 9.2.4 ?

Thanks.

The manual page you link to is for a command-line tool, not a function which runs inside the database itself, so will not show up when interrogating system views for available extensions.

Although the Debian package description doesn't mention it, the list of files included does. The list includes both /usr/lib/postgresql/9.2/bin/pg_test_fsync and /usr/share/postgresql/9.2/man/man1/pg_test_fsync.1.gz, so once that package is installed, you should be able to type man pg_test_fsync to confirm the options supported.
