No, I believe I fixed it: the table now offers
regexp_replace ( string text, pattern text, replacement text [, flags text ] )
→ text
regexp_replace ( string text, pattern text, replacement text, start integer [,
N integer [, flags text ] ] ) → text
That's different from either of the solutions discussed in this
thread, but simpler.

AFAICS, that one is correct, so I left it alone. (I didn't try to
merge the table's two entries into one like that, though.)
