DB2 compatibility environment for PostgreSQL

db2fce, a DB2 compatibility environment for PostgreSQL

This extension provides a variety of DB2 functions, types and operators for PostgreSQL.

All functions, types and operators are created in the db2 schema. Adding this to the search_path allows for unmodifed use of (some) DB2 SQL statements.

Note that some of the provied functions like INT() still need to be schema-qualified.

SYSIBM.SYSDUMMY1

DB2 SELECT statesments require a FROM clause with a table or view, even if no table/view columns are returned (as in PostgreSQL's "SELECT 1;"). In this case, the SYSIBM.SYSDUMMY1 view is customary used by DB2. The SYSIBM schema and this view is provided by db2fce.

Installation

Running make install installs the extension.

If pg_config is not found, you might have to pass its location via the PG_CONFIG environment variable.

Test Suite

An incomplete test suite is available. It can be exercised via make installcheck. The user running the testsuite probably needs elevated privileges in the contrib_regress database.
