Don't try to allocate the default value for a string relopt in the same palloc chunk as the relopt_string struct. That didn't work too well if you added a built-in string relopt in the stringRelOpts array, as it's not possible to have an initializer for a variable length struct in C. This makes the code slightly simpler too. While we're at it, move the call to validator function in add_string_reloption to before the allocation, so that if someone does pass a bogus default value, we don't leak memory. |
