Tom Lane 2f93b74bf3 Fix dumping of matviews with indirect dependencies on primary keys. Commit `62215de29` turns out to have been not quite on-the-mark. When we are forced to postpone dumping of a materialized view into the dump's post-data section (because it depends on a unique index that isn't created till that section), we may also have to postpone dumping other matviews that depend on said matview. The previous fix didn't reliably work for such cases: it'd break the dependency loops properly, producing a workable object ordering, but it didn't necessarily mark all the matviews as "postponed_def". This led to harmless bleating about "archive items not in correct section order", as reported by Tom Cassidy in bug #15602. Less harmlessly, selective-restore options such as --section might misbehave due to the matview dump objects not being properly labeled. The right way to fix it is to consider that each pre-data dependency we break amounts to moving the no-longer-dependent object into post-data, and hence we should mark that object if it's a matview. Back-patch to all supported versions, since the issue's been there since matviews were introduced. Discussion: https://postgr.es/m/15602-e895445f73dc450b@postgresql.org		2019-02-04 17:20:02 -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:

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
