This adds a new system function, pg_get_database_ddl(database_name/database_oid, ddl_options),
which reconstructs the CREATE DATABASE statement for a given database name or database oid.
Supported ddl_options are 'pretty', '--no-owner', '--no-tablespace' and '--with-defaults'.
Usage:
SELECT pg_get_database_ddl('postgres'); // Non pretty-formatted DDL
SELECT pg_get_database_ddl(16835); // Non pretty-formatted DDL
SELECT pg_get_database_ddl('postgres', 'pretty'); // pretty-formatted DDL
SELECT pg_get_database_ddl('postgres', '--no-owner', '--no-tablespace'); // Omits the Owner and Tablespace clause from the DDL.
SELECT pg_get_database_ddl('postgres', 'pretty', '--with-defaults'); // Includes clauses for parameters that are currently at their default values.
