Indeed, my first attempt to use arrays was to maintain some basic
statistics about a set of data. The array elements where to be
distribution moments and would only be used in "where" clauses. The
problem was that I wanted to be about to update the statistics using
triggers whenever the main data was updated. The inability to access
a specific array element in PL/pgSQL code made this so painful I ended
up just extending a table with more columns.
