Regina Obe d7b3ee51af Allow @extschema:<extname>@ in extension scripts
This feature allows an extension author to reference
extension schemas of extensions in the requires variable
of the control file using variable syntax
@extschema:<extname>@  where <extname> is the
name of any of the listed required extensions.

It also defines another optional config parameter
in the control file called no_relocate
which consists of a subset of the requires extensions
that should have ALTER EXTENSION SET SCHEMA prevented.

This feature is needed particularly in cases
when another extension packages a function
which references an object from one of its
required extensions and this function is used to back
indexes, constraints, and materialized views.

Without this feature, because pg_restore removes the paths,
these indexes, constraints, materialized views are not restored
because when the function is called, the function call fails
because items it depends on cannot be schema qualified.

This feature will allow extension authors to schema qualify
references to required extension objects to prevent this issue.
Aside from this issue, schema qualifying all these references will
improve security by preventing a rogue version of a function from being

 - Extension tests both Makefile and meson.build
 - Documentation of the new feature
 - Define a new extension control parameter no_relocate
   Which is a comma separated list of required extensions
   that should be prevented from ALTER .. SET SCHEMA
 - Prevent an extension from being relocated if
   another extension requires it and has it
   listed in it's no_relocate list
 - Change execute_extension_script to take as input
   required extension oids,
   since calling functions already build this list

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
