Hello! Does SQLAlchemy use E'' escapes for PostgreSQL? Postgres recommends
<https://www.postgresql.org/docs/8.1/static/sql-syntax.html#SQL-SYNTAX-CONSTANTS,>
using E'' since version 8.1 (released in 2005) and requires it since… not
sure, I think since 9.0 or 9.1.
I.e. when I want to insert 'xy\\nzy' instead of
INSERT INTO test (somestring) VALUES ('xy\\\\nzy');
SA should execute
INSERT INTO test (somestring) VALUES (E'xy\\nzy');
Currently I use SQLAlchemy 0.7.3 (yes, I know it's old, I'm ready to
upgrade) and Postgres issues warnings like this: "WARNING: nonstandard use
of escape in a string literal."
