- Added a routine by which the Postgresql Alembic dialect inspects
the server default of INTEGER/BIGINT columns as they are reflected
during autogenerate for the pattern ``nextval(<name>...)`` containing
a potential sequence name, then queries ``pg_catalog`` to see if this
sequence is "owned" by the column being reflected; if so, it assumes
this is a SERIAL or BIGSERIAL column and the server default is
omitted from the column reflection as well as any kind of
server_default comparison or rendering, along with an INFO message
in the logs indicating this has taken place. This allows SERIAL/BIGSERIAL
columns to keep the SEQUENCE from being unnecessarily present within
the autogenerate operation.
fixes #73
