Thanks everyone for helping me! Especially, Hiroshi, Noel and Richard! Following Noel's suggestion I installed pgAdmin (II, 1.6.0). It connected fine and I could see values in the tables withoutany other changes to client and server PCs. So, I decided to try the same connection string that pgAdmin uses (I couldconveniently cut and paste it from pgAdmin window: thanks, pgAdmin!) - and it worked! The string was: Provider=MSDASQL.1;Extended Properties="DRIVER={PostgreSQL};DATABASE=lara; SERVER=192.168.1.2;PORT=5432;UID=lara;PWD=********; ReadOnly=0;Protocol=6.4;FakeOidIndex=0;ShowOidColumn=0; RowVersioning=0;ShowSystemTables=0;ConnSettings=;Fetch=100; Socket=4096;UnknownSizes=0;MaxVarcharSize=254; MaxLongVarcharSize=65536;Debug=0;CommLog=0;Optimizer=1;Ksqo=1; UseDeclareFetch=0;TextAsLongVarchar=1;UnknownsAsLongVarchar=0; BoolsAsChar=1;Parse=0;CancelAsFreeStmt=0; ExtraSysTablePrefixes=dd_;LFConversion=1;UpdatableCursors=1; DisallowPremature=0;TrueIsMinus1=0;BI=0;ByteaAsLongVarBinary=0; UseServerSidePrepare=0" I think the problem was that when I specified a file DSN or would build a connection string using Delphi's tools it was nothandled properly or constructed properly by Delphi's TADOConnection object. So, what OLE DB driver for ODBC would getwas partially illegal; so, the driver would connect but would not communicate beyond the handshake. Now, the driver's log contains no errors (so, there was something serious there, Hiroshi). And I am going to try Richard'ssuggestion: run odbc.sql against the database. But my question is: Where can I get odbc.sql? I installed my PostgreSQL 7.3.2 from RPMs (Mandrake 9.1) and it was not in any contrib dirs. I also searched PostgreSQL,GBorg and Google sites with no success.

I am a newbie to ADO/ODBC so, I can't tell.
