@extschema:name@ extends the existing @extschema@ feature so that we can also insert the schema name of some required extension, thus making cross-extension references robust even if they are in different schemas. However, this has the same hazard as @extschema@: if the schema name is embedded literally in an installed object, rather than being looked up once during extension script execution, then it's no longer safe to relocate the other extension to another schema. To deal with that without restricting things unnecessarily, add a "no_relocate" option to extension control files. This allows an extension to specify that it cannot handle relocation of some of its required extensions, even if in themselves those extensions are relocatable. We detect "no_relocate" requests of dependent extensions during ALTER EXTENSION SET SCHEMA.

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/.
