Hmm ... tsvector_op.c has
/* Check if datatype is TEXT or binary-equivalent to it */
static bool
is_text_type(Oid typid)
{
/* varchar(n) and char(n) are binary-compatible with text */
if (typid == TEXTOID || typid == VARCHAROID || typid == BPCHAROID)
return true;
/* Allow domains over these types, too */
typid = getBaseType(typid);
if (typid == TEXTOID || typid == VARCHAROID || typid == BPCHAROID)
return true;
return false;
}
and a look at the caller says that "binary-equivalent to TEXT" is indeed
the requirement, because we want to apply DatumGetTextP() to the argument.
However, it does seem like this function is not implementing its
specification. Why isn't it just "IsBinaryCoercible(typid, TEXTOID)"?
