Hi, dear Cafe!

I'm having trouble compiling an application which uses PostgreSQL on a macbook with an M1 chip.

Postgre itself seems to work fine. It is installed via `homebrew` (if I'm not mistaken this is the only way on Mac to get pg_config, which is required for `persistent-postgresql`). The error message is following:

``` persistent-postgresql> <command line>: dlopen(/Users/arthurfayzrakhmanov/.stack/snapshots/x86_64-osx/36432054bd8d13c1da6134758733286b536c65d34222dcf10ecb29bd437c8117/8.10.7/lib/x86_64-osx-ghc-8.10.7/libHSpostgresql-libpq-0.9.4.3-GrxZELytXmSAOH6lAioiw9-ghc8.10.7.dylib, 5): *Symbol not found: _PQclear* persistent-postgresql> Referenced from: /Users/arthurfayzrakhmanov/.stack/snapshots/x86_64-osx/36432054bd8d13c1da6134758733286b536c65d34222dcf10ecb29bd437c8117/8.10.7/lib/x86_64-osx-ghc-8.10.7/libHSpostgresql-libpq-0.9.4.3-GrxZELytXmSAOH6lAioiw9-ghc8.10.7.dylib persistent-postgresql> *Expected in: flat namespace* persistent-postgresql> in /Users/arthurfayzrakhmanov/.stack/snapshots/x86_64-osx/36432054bd8d13c1da6134758733286b536c65d34222dcf10ecb29bd437c8117/8.10.7/lib/x86_64-osx-ghc-8.10.7/libHSpostgresql-libpq-0.9.4.3-GrxZELytXmSAOH6lAioiw9-ghc8.10.7.dylib ```

The minimal setup to reproduce is following:

``` dependencies: - base >= 4.7 && < 5 - persistent >= 2.13.1.2 && < 3 - persistent-postgresql >= 2.13.1.0 && < 3 ```

Digging around gave me just a few clues. It seems that `libpq` I have is compiled some other way it expected, and missing some symbols required `persistent-postgresql` to work. I believe this is not a bug, rather that a local configuration issue.

Does anyone know which is right setup to build persistent-postgresql on Macs with M1 chip? Thanks in advance.

Sincerely. Arthur.
