Assuming I understand what you want, you want to write a program in the C
language which interfaces with PostgreSQL. There are two methods to do
this. One is to use libpq and do everything in "regular C" with calls to
the libpq routines as documented here:
https://www.postgresql.org/docs/9.5/static/libpq.html . This is, IMO, the
more powerful interface, but it takes a lot more detailed programming on
your part.
The second way is with "embedded SQL" which may be a bit easier to write,
read, and understand. That is documented here:
https://www.postgresql.org/docs/9.5/static/ecpg.html .​
