problem of upper/lower case in table names

Hi all,

i've got this annoying problem : if you create a table with an uppercase
name, postgres transforms it in lower case. After that, if you try to
retrieve the primary keys for this table ( still using the uppercase
name as argument ) using the JDBC driver
DatabaseMetaData.getPrimaryKeys(), it always return an empty result set
since the SQL command used in the driver requests a case sensitive match
for the table name ( and bc.relname ~ table ).
I've a workaround in the driver ( using bc.relname ~* table ) but i'd
like to know who's fault it is ( mine or postgres ) ....
Thanks for your advices & help

NB : i'm using postgres 6.4 with jdbc driver included in this release.
