Tests fail on Postgres 11 and Up

[petergoldstein]

The specs fail when run on a more recent version of Postgres than 10.x, which EOLs this year. There are currently four more recent major versions - 11 - 14.

The failure is due to a change in syntax for trigger creation. In Postgres 10.x, the text EXECUTE PROCEDURE was included, as can be seen here - https://www.postgresql.org/docs/10/plpgsql-trigger.html

In later Postgres versions, this text was changed to EXECUTE FUNCTION as can be seen:

• https://www.postgresql.org/docs/11/plpgsql-trigger.html
• https://www.postgresql.org/docs/12/plpgsql-trigger.html
• https://www.postgresql.org/docs/13/plpgsql-trigger.html
• https://www.postgresql.org/docs/14/plpgsql-trigger.html

This mismatch causes specs to fail.

Is there any objection to updating the Postgres version in .travis.yml to 14? Making this change doesn't appear to impact the behavior of the gem, only whether the specs pass.
