Remember to reset yy_start state when firing up repl_scanner.l.
Without this, we get odd behavior when the previous cycle oflexing exited in a non-default exclusive state. Every othercopy of this code is aware that it has to do BEGIN(INITIAL),but repl_scanner.l did not get that memo.The real-world impact of this is probably limited, since mostreplication clients would abandon their connection after gettinga syntax error. Still, it's a bug.This mistake is old, so back-patch to all supported branches.Discussion:https://postgr.es/m/1874781.1643035952@sss.pgh.pa.us
