Hi I was surprised to find that whitespace is required between the != operator and a negative sign, otherwise postgres believes that I'm intending !=- as an operator (I get "operator does not exist: integer !=- integer"). This isn't the case with <>-x. Is this intentional? I couldn't find reference to it in the documentation (certainly not in http://www.postgresql.org/docs/9.5/static/functions-comparison.html). db=# SELECT 'yes' WHERE 1!=-1; ERROR: operator does not exist: integer !=- integer LINE 1: SELECT 'yes' WHERE 1!=-1; ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. Time: 0.608 ms db=# SELECT 'yes' WHERE 1<>-1; ?column? ---------- yes (1 row) I get this with fieldnames too, so it's not just a parsing-literal problem... This is on 9.5, also on 9.5.1. Geoff -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
