Added support for the infrastructure for on demand access/create the server connection. The BaseDriver and BaseConnection are two abstract classes, which allows us to replace the existing driver with the currently used. The current implementation supports to connect the PostgreSQL and Postgres Plus Advanced Server using the psycopg2 driver. 2015-10-20 12:33:18 +05:30			`from flask import current_app`
Optimise Python imports. 2016-06-21 14:12:14 +01:00

Added support for qtIdent, qtTypeIdent, qtLiteral for quoting the inputs. In order to do the proper quoting around the identifier, different type, and literal, we introduced respective functions qtIdent, qtTypeIdent, qtLiteral in psycopg2 driver. Also, introduced them as the Jinja's custom filter for using it directly inside the templates. Also, created an utility - generate_keywords.py in order to generate keyword lists from the latest PostgreSQL installation. 2016-01-02 14:54:01 +05:30			`return drivers`
