PostgreSQL Global Temporary Tables

pgtt is a PostgreSQL extension to create, manage and use DB2 or Oracle-style Global Temporary Tables. Once created the use is just like with the other RDBMS.

pgtt v4.5 has been released, this is a maintenance release to add support to PG 19 and add support to CREATE INDEX CONCURRENTLY. and fix issues reported by users since last release.

• Fix -Wmissing-variable-declarations warnings by making globals static.
• Remove use of the registered relid of the relation. When restoring pgtt_schema.pg_global_temp_tables from a dump it contains invalid Oid for the relation. Thanks to sibowu-aws for the report.
