DiffGenerator line 56 preg_match(): Argument #2 ($subject) must be of type string, int given

[jochen-jung]

Bug Report

When a table name is integer, like (211), then the DiffGenerator fails with the error:

preg_match(): Argument #2 ($subject) must be of type string, int given

Q	A
BC Break	no
Version	3.9.0

Summary

Though 211 is a bad table name, it still should not break the migration generation.

Current behavior

preg_match(): Argument #2 ($subject) must be of type string, int given

How to reproduce

Create a table named 211.

Run: bin/console doctrine:migrations:diff

Expected behavior

The migration should be generated
