Load configuration in post_parse_analyze hook

[rjuju]

Hello,

During testing, I found a corner case issue. If the first query executed on the cluster after a restart is a DROP TABLE of a partitionned table, it'll fail because the configuration will be loaded after the effective drop, but with the pathman_config table not up to date.

This commit moves the load_config() call to post_parse_analyze hook, which is also called for utility statement. If the overhead of calling a hook for every query just for this purpose is too much, ProcessUtility hook could be used instead, but the load_config() call would be duplicated. Let me know what you prefer.
