this week i

discovered an unknown park close to my father's home.  he sat in the car.

ate easter brunch, also nearby.  dad, give us a smile.

learned the hard way to live within ram whenever possible.  touching the disk requires i/o, grinds down on speed.  don't do this..

    CREATE TABLE a AS SELECT ...some stuff.. FROM b WITH DATA ;
    CREATE TABLE d AS SELECT ...other stuff.. FROM a WITH DATA ;
   
    ..instead, do this.
   
    CREATE TABLE d AS ( SELECT ..other stuff.. FROM ( SELECT ..some stuff.. FROM b ) AS a ) WITH DATA ;
