Completely broken on v0.6

[essenciary]

Sadly, this package is now completely broken on 0.6 :(

I started patching it but got stuck at

const _IO_FILE = Void

might work, not sure

Where was _IO_FILE defined before? i.e. how did this code ever work? Or did you re-run Clang or something?

This is apparently used for C FILE* arguments, which are opaque pointers, so just Void should work.

A more basic issue, however is that libpq_interface.jl (the Clang-generated file) is picking up a whole bunch of C standard-library functions (fscanf, perror, etcetera) that you almost certainly don't need or want. Probably you just want to include the PQ* functions (PQuser etcetera) and filter out everything else.

Current master works on 0.4.

It looks like libpq-fe.h includes stdio...maybe Clang.jl has an exclude list now. I ran it a very long time ago.

how did this code ever work

ccall used to be oddly permissive of invalid code in parts it didn't use or call

[stevengj]

Probably easiest to just manually trim the unnecessary functions from that file for now. It is not very long, and the API seems small enough to maintain the wrappers manually.
