I should probably explain this in a little more detail.

This was an attempt to build pg_thrift with PostgreSQL 10 (compiled from
REL_10_STABLE branch). Same issue with upcoming 11 version. I believe
you are testing the extension on some 9.x branch and don't see these
errors. Corresponding change in the API was done quite a long time ago,
in 2015 (see commit 13dbc7a8).

To solve this issue you can either use #ifdef's and maintain two
versions of the code for different versions of PostgreSQL or just
support only 10+. Both options are fine, at least by me personally.
