In PostgreSQL it is possible at CREATE TABLE time to set some extra storage parameters, the most useful of them in the context of pgloader being the FILLFACTOR. For the setting to be useful, it needs to be positionned at CREATE TABLE time, before we load the data. The BEFORE LOAD clause of the pgloader command allows to run SQL scripts that will be executed before the load, and even before the creation of the target schema when pgloader does that, which is nice for other use case. Here we implement a new `ALTER TABLE` rule that one can set in the pgloader command in order to change storage parameters at CREATE TABLE time: ALTER TABLE NAMES MATCHING ~/\./ SET (fillfactor='40') Fix #516.
