   EOModeler is a GUI tool to model the database schema as well as the
mapping between database records and EnterpriseObjects. The version
I'm using comes with database adaptors for Oracle, Sybase,Informix,LDAp
FlatFile,Openbase and ODBC.
   I've used EOModeler with many differenct databases including most of the
above, plus SQL server , MySQL, Access (via ODBC). All worked very well.
   But PostgreSQL+pgsqlODBC8.0 not work properly with EOModeler. I
can connect the database fine with EOModeler (can fetch all records in
specified
table within EOModeler), however, EOModeler cannot get the necessary info
about PostgreSQL data types. Below are the comparison of responses between
pgsql odbc 8.0 and myodbc 3.5 when EOModeler tries to get the meta info,
which
show that pgsql odbc reports nothing about the 'typeInfo' expected by
EOModeler,
while myodbc reports all 'typeInfo' (shown below). Consequently, EOModeler
and
related framework know nothing about how to talk to pgsql database properly.
By manully editing the typeInfo that EOModeler obtained and saved (as a text
file),
EOModeler starts working with pgsql. My editing was based on some guess and
the info from myodbc+mysql; which is not complete nor reliablel. can someone
help
me to get a complete typeInfo based one the following comparison? Thanks a
lot.
