Description:

Hello:

This documentation issue is for 9.6 (I don't know if it also applies for
9.5, but I am sure it does not apply for 9.4)

In section 36.9.9
https://www.postgresql.org/docs/current/static/xfunc-c.html

says:

uint32 call_cntr;
...
uint32 max_calls;

based on:
http://doxygen.postgresql.org/funcapi_8h_source.html#l00057

It should say:

uint64 call_cntr;
...
uint64 call_cntr;
