Description:        Enhancement Request - CONCAT() function
Details:

I would like the option to use CONCAT(field1, ' ', field2) instead of the
vertical bar syntax (field1 || ' ' || field2) as this is also available in
other popular databases (MySQL, ORACLE). I am trying to develop applications
which are daabase independent, so the use of common SQL syntax is very
important.
