v0.8.0: Postgres facade for driving BI tools
SLayer 0.8.0: Add a Postgres facade for driving BI tools
Adds a Postgres facade, that is SLayer can now pretend to be Postgres so that BI tools can use it as a data source. If you point Metabase (or another BI tool that speaks the Postgres wire protocol) at SLayer, the queries it generates now translate and run correctly across schema introspection, breakouts, filters, and joins.
Dialect fixes
Several SQL-generation bugs are fixed for SQL Server (CTE inside a derived table, dotted ORDER BY references) and MySQL (identifier quoting when a query is wrapped in an outer select).
