Mystring = gvk | gvk1 | gvk2

Answer 1

The MS SQL to POSTGRES Blogspot has a demonstration of how to implement a group_concat function in Postgres. It should be pretty straightforward to modify it to include a separator

Answer 2

I think you can use the array_to_string function here :

array_to_string(anyarray, text) --> text
concatenates array elements using supplied delimiter

e.g. array_to_string(ARRAY[1, 2, 3], '~^~') --> 1~^~2~^~3
