Обсуждение: pgsql: Allow trailing whitespace in parse_real(), for consistency with

Log Message:
-----------
Allow trailing whitespace in parse_real(), for consistency with
parse_int() and with itself (strtod allows leading whitespace, so it
seems odd not to allow trailing whitespace).  parse_bool remains
not-whitespace-friendly, but this is generically true for non-numeric
GUC variables, so I'll desist from changing it.
