Adding SQLITE_ENABLE_DBSTAT_VTAB

[mikeburgh]

This enables the virtual stats table in SQLite https://www.sqlite.org/dbstat.html

Neat! First time I’ve seen this feature. Is there any performance penalty to enabling this?

[mikeburgh]

Not that I have witnessed, and a bit of digging through the forums turned up this:

"SQLITE_ENABLE_DBSTAT_VTAB enables the dbstat virtual table. This will make the executable bigger, but should not impact performance if it is not used."

It is usually activated in other builds I know of.

• ✅ the precompiled binaries have it
• ✅ the Homebrew version have it
• ✅ the other node package node-sqlite have it

I would love better-sqlite3 to have it cause I really need it🙏

adding an example use-case to motivate the merge:

Many apps will allow people to store custom json or binary blobs in their DB => many users may by mistake blow up their DB size by doing something wrong => many devs will want a quick way to see if table size (count and size) make sense.
