Die Energy-Charts bieten interaktive Grafiken zu: Stromproduktion, Stromerzeugung, Emissionen, Klimadaten, Spotmarktpreisen, Szenarien zur Energiewende und eine umfangreiche Kartenanwendung zu: Kraftwerken, Übertragungsleitungen und Meteodaten
Willkommen! Wir möchten mit dieser Webseite einen Beitrag zur Transparenz und Versachlichung der Diskussion um die Energiewende leisten.
Die Rohdaten werden von Wissenschaftlern des Fraunhofer-Institut für Solare Energiesysteme ISE aus zahlreichen Quellen stündlich oder täglich abgerufen und für die Darstellung aufbereitet.
Basically there are 4 steps:
Rename old table
Create new table
with partitioning
Add constraint on old table for it's proposed partition ranges
Attach old table as a partition to new partition table
Sounds easy right?
What about indexes? What about Triggers?
And guess what, there are other traps to watch out for!
-- Add the check constraint
alter table public.test_partition_10_25 add constraint test_partition_10_25_constraint CHECK (id >= 10 AND id <25) NOT VALID;
update pg_constraint pgc
SET convalidated = true
FROM pg_class c
WHERE
c.oid = pgc.conrelid
AND connamespace = 'public'::regnamespace::oid
AND c.relname = 'test_partition_10_25'
AND conname = 'test_partition_10_25_constraint';

A SequenceInputStream represents the logical concatenation of other input streams. It starts out with an ordered collection of input streams and reads from the first one until end of file is reached, whereupon it reads from the second one, and so on, until end of file is reached on the last of the contained input streams.
pgloader will keep a separate file of rejected data, but continue trying to copy good data in your database.
pgloader also implements data reformatting, a typical example of that being the transformation of MySQL datestamps 0000-00-00 and 0000-00-00 00:00:00 to PostgreSQL NULL value
