failOnError does not abort generation

[KieranKaelin]

Describe the bug
@pgtyped/cli does not respect the failOnError flag during generation.

Expected behavior
The workers should stop, and the process should exit with code 1.

Test case

• In packages/example, add "failOnError": true to config.json
• In any of the *.sql files, modify a statement to be incorrect.
• Execute npm run typegen
• The error will appear in the log, but execution does not stop, and echo $? returns 0

From my novice eye, it seems that this regression stems from e5f920e (as cdfadfb, the previous commit, is working as expected), specifically the changes in packages/cli/src/index.ts#L40.

I made a quick local test, replacing this.pool.run(opts, { name: functionName }); with

const result = await this.pool.run(opts, { name: functionName });
if (result.error) {
  throw result.error;
}
return result;

Rerunning npm run typegen now behaves as expected, immediately stopping all workers as it encounters the erroneous file, and exiting with code 1.

Here's an unfortunate workaround for those who butt up against this

pgtyped -c ./pgtyped.config.cjs 2>&1 | tee  /dev/tty | grep 'Error:' && exit 1 || exit 0
