The PHP source code (ext/pgsql/pgsql.c) doesn't have any calls to
PQfformat or PQbinaryTuples so PHP appears to expect text data.
Looks like you'll have to fetch data in text format and use
pg_unescape_bytea.
Maybe the PHP developers would consider adding support for binary
data (or maybe they already have and rejected the idea; I don't
know). Try asking on a PHP mailing list.
