Removes a conversion.
DROP CONVERSION [IF EXISTS] <name> [CASCADE | RESTRICT]
DROP CONVERSION removes a previously defined conversion. To be able to drop a conversion, you must own the conversion.
IF EXISTS
Do not throw an error if the conversion does not exist. A notice is issued in this case.
name
The name of the conversion. The conversion name may be schema-qualified.
CASCADE RESTRICT
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 Apache Cloudberry CREATE CONVERSION and DROP CONVERSION statements.
