Michael Paquier 3ad8b840ce Add some tests for encoding conversion in COPY TO/FROM 
This adds a couple of tests to trigger encoding conversion when input
and server encodings do not match in COPY FROM/TO, or need_transcoding
set to true in the COPY state data.  These tests rely on UTF8 <-> LATIN1
for the valid cases as LATIN1 accepts any bytes, and UTF8 <-> EUC_JP for
some of the invalid cases where a character cannot be understood,
causing a conversion failure.

Both ENCODING and client_encoding are covered.  Test suggested by Andres
Freund.
