Notes for Actian Avalanche, Vector, ActianX, and Ingres.
This branch can be used with Actian database without special config when used with https://github.com/clach04/ingres_sa_dialect
Alternatively upstream/master can be used with a simple config change to superset/config.py, set:
SQL_MAX_ROW = 0
This removes all LIMIT clauses from queries.
