Tom Lane f3316a05b5 Fix pg_restore's direct-to-database mode for INSERT-style table data. In commit `6545a901aa`, I removed the mini SQL lexer that was in pg_backup_db.c, thinking that it had no real purpose beyond separating COPY data from SQL commands, which purpose had been obsoleted by long-ago fixes in pg_dump's archive file format. Unfortunately this was in error: that code was also used to identify command boundaries in INSERT-style table data, which is run together as a single string in the archive file for better compressibility. As a result, direct-to-database restores from archive files made with --inserts or --column-inserts fail in our latest releases, as reported by Dick Visser. To fix, restore the mini SQL lexer, but simplify it by adjusting the calling logic so that it's only required to cope with INSERT-style table data, not arbitrary SQL commands. This allows us to not have to deal with SQL comments, E'' strings, or dollar-quoted strings, none of which have ever been emitted by dumpTableData_insert. Also, fix the lexer to cope with standard-conforming strings, which was the actual bug that the previous patch was meant to solve. Back-patch to all supported branches. The previous patch went back to 8.2, which unfortunately means that the EOL release of 8.2 contains this bug, but I don't think we're doing another 8.2 release just because of that.		2012-01-06 13:04:09 -05:00

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:

	http://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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
