pgsql: Harmonize function parameter names for Postgres 19.

Harmonize function parameter names for Postgres 19.

Make sure that function declarations use names that exactly match the
corresponding names from function definitions in a few places. Most of
these inconsistencies were introduced during Postgres 19 development.

This commit was written with help from clang-tidy, by mechanically
applying the same rules as similar clean-up commits (the earliest such
commit was commit 035ce1fe).
