It is not 100% compatible but I think it implements all pgsql requirements, only
the version in ports and he head handle correctly unicode.

Some of the default settings are a bit different most ^W but that can be changed
via .editrc

mysql has tips about the differences:
https://docs.oracle.com/cd/E17952_01/refman-5.6-en/mysql-tips.html

From what I can read in the code psql only uses compatible interfaces.

As the one who have done the latet updates on libedit both base and ports, I
would recommand to only use the version from ports on all version of FreeBSD as
I can add quick fixes if needed.

Once I'm sure the libedit in base is good enough everywhere we would be able to
switch on the base version if people prefers to avoid an external dep.
