OK, I will send patch for this and send domumentation for all 
oracle_compat.c routines...
I don't want make some changes to contrib/odbc, because it's out of
me... but I have a question, Why in the contrib/odbc/odbc.c are total
same function as in oracle_compat.c (like ascii(), ichar(), repeat())?  

Is it anything specific for ODBC?
