Possible to have array as input paramter for a function?

Dear Friends,
 
I am working with Postgres 7.3.4 on RH Linux 7.2 and my windows client is PgAdmin 3.
 
Is it possible to pass a Varchar[] as a input parameter for a PL/pgSQL function. While I tried it give a error
    Type "varchar[]" does not exists.
 
Does this is supported in Postgres?
 
Anyone have a link or while paper on handling arrays in functions?
 
Please enlighten me on this.
 
Regards
Kumar

Hi Kumar,
 
It is possible to pass an array to a PL/pgSQL function, but I believe you must specify the length of the array (at least doing so works for me). E.g. "varchar(20)".

George

Hi Kumar,
 
Looks like I got up too early this morning - please ignore my previous reply re: varchar(30) (I was looking at the wrong function :-(  ).
 
I do use arrays in Pl/pgSQL functions, and have defined them as you did, e.g. varchar[], which does not return an error.  What version of PostgreSQL are you using?  I am running 7.3.2.

George
