The suggestion works fine w/recent versions; perhaps it's a '6.3
thing'

Perhaps

SELECT * FROM tbl WHERE chromat::TEXT ~~ ('%' || sample || '%'
)::TEXT;

?

Also, upgrading isn't difficult in most cases; you can pg_dumpall and
upgrade and restore your files. 7.0 has many nice features over the
6.x series.
