Commit Message

Add operator class between int and numeric to support index scan (#3761)

Earlier, index scan would not be chosen by the optimizer when filtering between
int and numeric types if the index was created on a numeric column. While index
scans worked when the index was on an integer column (due to existing operator
class as part of int operator family), the reverse case wasn't supported.

This commit fixes this issue by adding a new operator class as part of the numeric
operator family which allows the optimizer to utilize indexes on numeric columns when
filtering with integer values, improving query performance in these scenarios.

This changes also requires engine changes (babelfish-for-postgresql/postgresql_modified_for_babelfish#576)
in order to dump these Babelfish defined operator class correctly during pg_upgrade.
