Michael Paquier 27e0ee57f6 Fix path reference when parsing pg_ident.conf for pg_ident_file_mappings
Since a2c8499, HbaFileName (default pg_hba.conf) was getting used
instead of IdentFileName (default pg_ident.conf) as the parent file to
use as reference when parsing the contents of pg_ident.conf, with
pg_ident.conf correctly opened, when feeding this information to
pg_ident_file_mappings.  This had two consequences:
- On an I/O error when reading pg_ident.conf, the user would get an
ERROR message referring to pg_hba.conf and not pg_ident.conf.
- When reading an external file with a relative path using '@' in
pg_ident.conf, the directory used to look at the file to load would be
the base directory of pg_hba.conf rather than the one of pg_ident.conf,
leading to errors in pg_ident_file_mappings inconsistent with what gets
loaded at startup when pg_ident.conf and pg_hba.conf are located in
different directories.

This error only impacted the SQL view pg_ident_file_mappings that uses a
logic new to v15 to fill the view with the parsed information, not the
code paths loading these authentication files at startup.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.
