Thanks for updating the patch!

+						(errcode(ERRCODE_INVALID_PARAMETER_VALUE),
+						 errmsg("invalid numeric value for option \"%s\"",
+								def->defname)));

In reloptions.c, when parse_real() fails to parse the input, the error message
"invalid value for floating point option..." is output.
For the sake of consistency, we should use the same error message here?

-						(errcode(ERRCODE_SYNTAX_ERROR),
-						 errmsg("%s requires a non-negative integer value",
+						(errcode(ERRCODE_INVALID_PARAMETER_VALUE),
+						 errmsg("invalid integer value for option \"%s\"",

IMO the error message should be "invalid value for integer option..." here
because of the same reason I told above. Thought?
