How are you "exporting" a MS SQL table to PG? If this is a dump utility in
MS SQL, there may be an option in this dumping program to not quote
identifiers (table names, etc.) to be uppercase.
However, if the dumping program is dumping with quoted uppercase
identifers, it's not a bug that PG doesn't find the table: "TEST" is a
different table than "test". This is not an ODBC problem at all, if I
understand your problem.
Unquoted identifiers, eg test (no quotes) is sent as uppercase regardless
of how you write it: test Test teST; if written w/quotes, case is
preserved.
If the MSSQL dump routine can't ditch the quoted identifiers, you could
either (a) search/replace/sed/perl/whatever the quotes out of the SQL dump
before importing to PG, or (b) once in PG, ALTER TABLE "FOO" RENAME TO
"foo".
(b) is tricky, though, as index names and ref integrity constraints and
such aren't corrected for this. (a) is a better solution.
