[Haskell-cafe] Troubles with PostgreSQL, Persistent and Apple M1

[Geraldus]

Thank you for your response.

I use 13.4:

```
arthurfayzrakhmanov at MacBook-Pro-Arthur ~/L/h/pg001> brew search postgres
==> Formulae
check_postgres      postgresql at 11       postgresql at 9.5      qt-postgresql
postgresql ✔        postgresql at 12       postgresql at 9.6      postgis
postgresql at 10       postgresql at 9.4      postgrest
==> Casks
navicat-for-postgresql                   postgrespreferencepane
postgres-unofficial                      sqlpro-for-postgres
arthurfayzrakhmanov at MacBook-Pro-Arthur ~/L/h/pg001> psql --version
psql (PostgreSQL) 13.4
```
