When using a prepared statement to select data from a PostgreSQL foreign table (postgres_fdw) with the "field = ANY($1)" expression, the operation is not pushed down when an implicit type case is applied, and a generic plan is used. This commit resolves the issue by supporting the push-down of ArrayCoerceExpr, which is used in this case. The support is quite straightforward and similar to other nods, such as RelabelType.
