Tom Lane 8ec00dc5cd Remove undesirable libpq dependency on stringinfo.c. 
Commit c0cb87fbb unwisely introduced a dependency on the StringInfo
machinery in fe-connect.c.  We must not use that in libpq, because
it will do a summary exit(1) if it hits OOM, and that is not
appropriate behavior for a general-purpose library.  The goal of
allowing arbitrary line lengths in service files doesn't seem like
it's worth a lot of effort, so revert back to the previous method
of using a stack-allocated buffer and failing on buffer overflow.

This isn't an exact revert though.  I kept that patch's refactoring
to have a single exit path, as that seems cleaner than having each
error path know what to do to clean up.  Also, I made the fixed-size
buffer 1024 bytes not 256, just to push off the need for an expandable
buffer some more.

There is more to do here; in particular the lack of any mechanical
check for this type of mistake now seems pretty hazardous.  But this
fix gets us back to the level of robustness we had in v13, anyway.

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:

	https://www.postgresql.org/download/

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.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
