I am told that SQLite compiles and runs out-of-the-box on Integrity  
OS.  No porting necessary.  But not having a license for Integrity OS  
nor hardware to run it on, I've never actually tried this myself.

The TH3 test suite has been run successful on SQLite on Integrity OS,  
I am told.

Please see http://www.sqlite.org/faq.html#q19

If WLFS is still to slow for you, you can build your database on a  
workstation and then copy the whole thing over to your device.  The  
database files are cross-platform.

Really?.  A lowly user process like SQLite can panic the filesystem?   
How is that possible? Isn't Integrity OS suppose to be a super-high- 
reliability operating system?  And the filesystem can panic?
