Thread: pgsql: Simplify logic to sync target directory at the end of pg_rewind

Simplify logic to sync target directory at the end of pg_rewind

The previous sync logic relied on looking for and then launching
externally initdb -S, which is a simple wrapper on top of fsync_pgdata.
There is nothing preventing pg_rewind to directly call this routine, so
remove the dependency to initdb and just call it directly.
