Copy RecordArray from pgtype to database

Debian’s pgtype version is 1.10.0, but pgtype did not add RecordArray
type until 1.11.0, thus could not compile the application with
Debian 12.

I just copied the code from 1.11.0 without any modification besides
adding the reference to the pgtype package to types and functions.
