Maybe, but you haven't shown us a reproducible example.
What I get from the fragments you gave here is

ERROR:  ptest(text[]) is not a procedure
LINE 1: CALL ptest( test )
             ^
HINT:  To call a function, use SELECT.
QUERY:  CALL ptest( test )
CONTEXT:  PL/pgSQL function inline_code_block line 6 at CALL

I suspect that the underlying problem may involve a SQL declaration
for "ptest" that doesn't match what the C code does, so I'm not going
to guess at what you actually used as the SQL declaration.  But
clearly it's not what you wrote here.
