Test failure with PG12

[df7cb]

pg_rational is almost compatible with PG12beta1, it just fails one test because of the new ryu float output format:

A possible fix would be to put SET extra_float_digits = 0; into the test file.

A new release with the fix would be appreciated for us packagers. Thanks!

pg_rational is *almost* compatible with PG12beta1, it just fails one test because of the new ryu float output format:

Thanks for testing on the beta and letting me know about the upcoming change.

A possible fix would be to put `SET extra_float_digits = 1;` into the test file.

Great, I'll give that a try and if it works on both pg12 and earlier versions, I'll create a tag and release.

Fwiw, it's actually e_f_d = 0, I fixed the typo in my original posting.
