Troubles with JDBC method DataBaseMetaData.getTables()

Hi PostgreSQL developers,

I am having trouble with PostgreSQL's implementation of DataBaseMetaData.getTables() and looking at the code I found this comment and so I am writing to you.

The problem I am having is that If I create tables with uppercase letters like this

create table "FOO" ( "NUM" numeric );

then I can´t use this code to check if the table exists

ResultSet rs = conn.getMetaData().getTables( null, null, "FOO", null );
Boolean exists = rs.next();

I suppose it´s because the tableNamePattern is being converted toLowerCase()

// Added by Stefan Andreasen <stefan@linux.kapow.dk>
// Now take the pattern into account
sql.append(") and relname like '");
sql.append(tableNamePattern.toLowerCase());
sql.append("' order by relkind, relname");

I suggest to eliminate this conversion and leave the user do the conversion if he desires.

Greetings
