Fixed the 4K character limit on session properties for Oracle by making an optional "clob" value available. The APM wouldn't let me load any packages when I added all the dotLRN packages plus standard packages over to a new "dotlrn" user from my normal "acs" user - the list of packages grew to > 4KB in size! Grrrr!
Renamed a column named "timestamp" in the security package because this is now a reserved word in PG (correctly). I changed the Oracle version, too, because I know that 9i has added the "timestamp" datatype and even if it will accept it as a column name it's confusing.
I also changes postgresql.sql to load correctly under PG 7.1 and 7.2.
