Thread: memory leak in psqlodb 08.04.0200
Hi, When i use DTS from mssql to export data to postgres and the table is > 1million i get an error: Out of memory while reading tuples. I'm trying to understand the issue so i changed log_min_duration_statement=-1 in postgresql.conf to get all statements executed and i get BEGIN; INSERT one row sent from the dts RETURNING ctid; SELECT WHERE ctid; COMMIT; and when i select count(*) from table i get the rows it migrated until now... so, obviously the psqlODBC should be free'ing the memory it used for that tuple but instead when i see the Task Manager in windows i see how the memory is going down until it gets to zero... so this should be a memory leak, no? how can i trace it in the psqlODBC? -- Jaime Casanova www.2ndQuadrant.com Soporte y capacitación de PostgreSQL
