pgsql: Avoid mixing designated and non-designated field initializers.

Avoid mixing designated and non-designated field initializers.

As revised by commit 9324c8c58, PG_MODULE_MAGIC constructed a
struct initializer containing both designated fields and a
non-designated "0". That's okay in C, but not in C++, with
the result that extensions written in C++ failed to compile.
Change it to use only designated field initializers.
