A colleague made some tests (not completely systematically, not a complete
test suite).
SAP DB performed considerably worse than PostgreSQL in these tests,
especially when the amount of data grew.

He also had some problems with the ODBC drivers and the SAP DB
admin tool.

He was transformed from a SAP DB enthusiast to an SAP DB doubter.

SAP DB has also the more restrictive GPL license model.
