fix PG_DATADIR initialization for cases when empty or contains too many files #152

Closed kkimurak closed 1 year ago

Previous implementation passed nothing to chmod when PG_DATADIR is empty. This results in chmod raises syntax error and wrong permissions will not be corrected : This is the cause of problem reported in sameersbn/docker-gitlab#2224
We also can see Argument list too long error when PG_DATADIR contains too many files / directories (restriction defined by ARG_MAX) : this is reported in #148

This PR make create_datadir() to handle those situations by using xargs.
