Tom Lane a4424c57c3 Remove unnecessary restrictions about RowExprs in transformAExprIn(). When the existing code here was written, it made sense to special-case RowExprs because that was the only way that we could handle row comparisons at all. Now that we have record_eq() and arrays of composites, the generic logic for "scalar" types will in fact work on RowExprs too, so there's no reason to throw error for combinations of RowExprs and other ways of forming composite values, nor to ignore the possibility of using a ScalarArrayOpExpr. But keep using the old logic when comparing two RowExprs, for consistency with the main transformAExprOp() logic. (This allows some cases with not-quite-identical rowtypes to succeed, so we might get push-back if we removed it.) Per bug #8198 from Rafal Rzepecki. Back-patch to all supported branches, since this works fine as far back as 8.4. Rafal Rzepecki and Tom Lane		12 years ago

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/.
