Teach convert() and friends to avoid copying when possible.
Presently, pg_convert() allocates a new bytea and copies the result
regardless of whether any conversion actually happened. This
commit adjusts this function to return the source pointer as-is if
no conversion occurred. This optimization isn't expected to make a
tremendous difference, but it still seems worthwhile to avoid
unnecessary memory allocations.
