I have used pgadminII to create a series of functions. However it appears that they are all all given array parameters. ( see the definition shown below) If I create the function manually with a return type of "bool" instead of "bool[]" all is ok. However if I use pgadmin then I get a horrible error
ERROR: array_in: Need to specify dimension
pgAdmin will happily create functions without using the array types - just select bool without the square brackets in the Returns combo box (check further down the list).
