Hmm.  Looks like there is a pg_operator entry for text[] = text[],
but none for bpchar[] = bpchar[].  This is an oversight, nothing more.
Feel free to add such an entry --- it can point to the same array-equals
function as the one for text[].

It's too late to fix this in the standard catalogs for 7.2, but I'll
make a note for 7.3.
