  This file is the tail end of the sqlite3-api.js constellation,
  closing the function scope opened by post-js-header.js.

  In terms of amalgamation code placement, this file is appended
  immediately after the final sqlite3-api-*.js piece. Those files
  cooperate to prepare sqlite3ApiBootstrap() and this file calls it.
  It is run within a context which gives it access to Emscripten's
  Module object, after sqlite3.wasm is loaded but before
  sqlite3ApiBootstrap() has been called.

  Because this code resides (after building) inside the function
  installed by post-js-header.js, it has access to state set up by
  pre-js.c-pp.js and friends.
