Override PGDialect initialize

bryanherger · bryanherger · commit 197776bef7e1 · 2018-10-14T23:54:34.000-04:00
PGDialect initialize sets a number of flags based on Postgres server version, but the Vertica server version doesn't match functionality.  Override the PGDialect implementation and set flags compatible with Vertica.
