We have an issue with images (TIFF files) that are loaded into a postgres database table (where the image field is defined as type “lo”). The code to load the images is written in VB and the connection to the database is through postgres odbc installed on the PC. All images inserted through the VB program are retrievable also through odbc/VB, as long as the table rows at the backend are not reorganized in any way. If the table data is unloaded/reloaded or clustered (on an index) or reloaded through a pg_dump and restore, then on trying to retrieve the images, the VB program gets the error : “Multiple-step OLE DB operation generated errors. Check each OLE DB status value……etc”.
The data in the backend database is still readable through other image retrieval programs connecting directly to the server (not through ODBC or VB).
Are you reloading into the very same database, or into a different one? Your question doesn't make it clear. If you're loading into a new database, then one thing that comes to mind is that the bytea_output parameter in postgresql.conf might be different on the second database.

The database is on an AIX server (version 6.1). Postgres version is 9.1.4.I’d welcome any input towards the resolution of this problem.Thanks.Alanoly Andrews
