Two functions exists that convert "text" to "text[]"
regexp_string_to_array(text, text [,text]) :
http://www.postgresql.org/docs/9.4/interactive/functions-string.html
string_to_array(text, text [, text]) :
http://www.postgresql.org/docs/9.4/interactive/functions-array.html
Would it be hateful to make it so that both entries appear on both tables?
array_to_string(anyarray, text [,text]) could be lumped in with this as
well.
string_to_array not being on the string functions page is the more glaring
omission for me.
