Tom Lane dc8d72c1c2 Collect dependency information for parsed CallStmts. 
Parse analysis of a CallStmt will inject mutable information,
for instance the OID of the called procedure, so that subsequent
DDL may create a need to re-parse the CALL.  We failed to detect
this for CALLs in plpgsql routines, because no dependency information
was collected when putting a CallStmt into the plan cache.  That
could lead to misbehavior or strange errors such as "cache lookup
failed".

Before commit ee895a655, the issue would only manifest for CALLs
appearing in atomic contexts, because we re-planned non-atomic
CALLs every time through anyway.

It is now apparent that extract_query_dependencies() probably
needs a special case for every utility statement type for which
stmt_requires_parse_analysis() returns true.  I wanted to add
something like Assert(!stmt_requires_parse_analysis(...)) when
falling out of extract_query_dependencies_walker without doing
anything, but there are API issues as well as a more fundamental
point: stmt_requires_parse_analysis is supposed to be applied to
raw parser output, so it'd be cheating to assume it will give the
correct answer for post-parse-analysis trees.  I contented myself
with adding a comment.

Per bug #18131 from Christian Stork.  Back-patch to all supported
branches.

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/.
