Redbean lua: why isn't sqlite3.backup_init function available?

[bjornbm]

Why isn't the function sqlite3.backup_init available in the lsqlite3 library in redbean?

I guess I can extend the question to the other functions that seem to be missing (sqlite.complete, sqlite.temp_directory, sqlite.open_ptr), but sqlite.backup_init was the one I was looking for right now.

FYI, here are the functions I see:

$ redbean -i
>: require'lsqlite3'
{
  …
  __newindex="func@0x80001d278",
  config="func@0x80001d2c8",
  lversion="func@0x80001d238",
  open="func@0x80001f5d8",
  open_memory="func@0x80001f598",
  version="func@0x80001d538"
}

Thanks!

It looks like it was removed in 88806b7 to keep the code more lean. Would vacuum into work for your use case? This is what I'm using for DB backups.
