Need postgresql helper to build arrays

[DrDeath72]

ArrayExpression build array with bind params, on big queries postgresql dies with params limit, need native simple helper to convert array to postgreslq array string like '{1,2,3,4}', '{1,2,3,4}::int[]'

I don't recall anyone asking for that before hence it looks like not a very essential feature. Can't it be solved using plain SQL instead? Anyway we could welcome such helper.

last issue is batchInsert exception with many ArrayExpression (> 65000), replace with custom toPgArray function :(
