Determining Array size - Mailing list pgsql-sql

I am trying to determine the number of elements in an array.

I looked through the list of loaded functions, and was unable to find one that 
seemed to provide this functionality. 

Is there some other means to detemine this?

I am new to postgresql and am still trying to learn the 'ordbms way' :-) 


thanks,
