post-js-header.js is to be prepended to other code to create
post-js.js for use with Emscripten's --post-js flag. This code
requires that it be running in that context. The Emscripten
environment must have been set up already but it will not have
loaded its WASM when the code in this file is run. The function this
file installs will be run after the WASM module is loaded, at which
point the sqlite3 JS API bits will get set up.
post-js.js for use with Emscripten's --post-js flag, so it gets
injected in the earliest stages of sqlite3InitModule().
This function wraps the whole SQLite3 library but does not
bootstrap it.
Running this function will bootstrap the library and return
a Promise to the sqlite3 namespace object.
