Howto determin the number of elemnts of an array

Hi,
how can I determin the number of elements of an array? I saw function
array_dims() which returns a string value representing the dimensions of the
array. Is there a function which returns only the number of elements as an
integer.

array_upper(arrayname,dimension) will return the number of elements in
the specified dimension of array arrayname.

Hi Seven,
it would be better for me if it returned the number of elements as an
integer even if the array is empty (in this case it returns with NULL). No
metter this is easily can be worked around, but it would have been more
confortable.

Thank you very much.

icount( array )

Hi,
this function is part of GiST which is not installed on my server. Should I
install the whole GiST or there is a single package to implement only this
feature?

thank you,

I really can't find such file in contrib dir. Nor files containing 'icount'
pattern. Sorry.
I use Pg8.0 final on windows XP.

On the http://www.sai.msu.su/~megera/postgres/gist/ url I can find only a
patch. Where can I download the whole package from?

Thank you.
