Thread:Project:Support desk/Database error (4)

I am using a native install of MediaWiki v1.22.1 with PostgreSQL. I have just started actively using the site...and most everything seems to work as expected until I attempt to save an edited page that contain external links. I get an error that reads:

The changes to the pages appear to be maintained...but I am curious what I could do to alleviate this error message or at least understand it a bit better. Any thoughts?
