2023-09-20fix: add check to sqlite extension loading logic (#5773)Gravatar Liz 2-0/+9
The sqlite3 logic to dynamically load extensions can be disabled to save space, which macos does by default. sqlite3 provides a api to check for these compile time settings at runtime, we can use that to throw a js error rather then crashing. It is worth noting though that the api to check for these settings at runtime itself can be disabled through SQLITE_OMIT_COMPILEOPTION_DIAGS but this seams to be a edge case.
