Re: [PATCH] Add inline comments to the pg_hba_file_rules view

This is a very useful feature. I applied the patch to the master branch,
and both make check and make check-world passed without any issues.

Just one comment here, based on the example below,

> host db jim 127.0.0.1/32 md5 #     #foo#
>
> ... it returns the following pg_hba_file_rules records:
>
> postgres=#  SELECT type, database, user_name, address, comment
>  FROM pg_hba_file_rules
>  WHERE user_name[1]='jim';
>
>  type | database | user_name |  address  | comment
> ------+----------+-----------+-----------+---------
>  host | {db}     | {jim}     | 127.0.0.1 | #foo#

Since "only the first #" and "any leading spaces" are removed, IMO, it
can be more accurate to say,

Text after the first <literal>#</literal> comment character in the end
of a valid <literal>pg_hba.conf</literal> entry, if any
