- Do not throw an error if the conversion does not exist. A notice is issued in this case.
- The name of the conversion. The conversion name may be schema-qualified.
- These keywords have no effect since there are no dependencies on conversions.
Drop the conversion named myname:
DROP CONVERSION myname;
There is no DROP CONVERSION statement in the SQL standard. The standard has CREATE TRANSLATION and DROP TRANSLATION statements that are similar to the Greenplum Database CREATE CONVERSION and DROP CONVERSION statements.
