[GitHub] [arrow-adbc] lidavidm opened a new issue, #701: c/driver/postgresql: infer schema by using a prepared statement

lidavidm opened a new issue, #701:
URL: https://github.com/apache/arrow-adbc/issues/701

   Would this have an impact on performance or server resources?
   
   [pqDescribePrepared](https://www.postgresql.org/docs/current/libpq-exec.html#LIBPQ-PQDESCRIBEPREPARED) gives you the columns of the result schema. That lets us infer the schema without the current `SELECT (*) LIMIT 0` hack, which breaks down for things that aren't SELECTs.

   I will probably do this first since the C++ equivalent of #700 would get much easier with this.
