The first error I'm seeing in the dblog when upgrading my current db to 1.4 is this one:
psql:sql/Pg-database.sql:4802: ERROR: column "gl.transdate" must appear in the GROUP BY clause or be used in an aggregate function
LINE 5: WHEN gl.transdate = ac.transdate
psql:sql/Pg-database.sql:4806: ERROR: current transaction is aborted, commands ignored until end of transaction block
And the browser reports the failed attempt.
