Hi everyone,

Consider the following statements:

CREATE TABLE t0(c0 TEXT);
CREATE INDEX i0 ON t0(c0 bpchar_ops);
SELECT * FROM t0 WHERE t0.c0 LIKE ''; -- ERROR:  no = operator for opfamily 426

Unexpectedly, the index seems to create problems for the subsequent
query. When replacing the TEXT type by CHAR, the statements execute
successfully. Should it be possible to use this opclass for the TEXT
type?

Best,
Manuel
