====== Mastodon - poznámky k instalaci ======

==== Chybky pri instalaci ====

  * PG::Error: ERROR: new encoding (UTF8) is incompatible

<code>


    First, we need to drop template1. Templates can’t be dropped, so we first modify it so t’s an ordinary database:

    UPDATE pg_database SET datistemplate = FALSE WHERE datname = 'template1';

    Now we can drop it:

    DROP DATABASE template1;

    Now its time to create database from template0, with a new default encoding:

    CREATE DATABASE template1 WITH TEMPLATE = template0 ENCODING = 'UNICODE';

    Now modify template1 so it’s actually a template:

    UPDATE pg_database SET datistemplate = TRUE WHERE datname = 'template1';

    Now switch to template1 and VACUUM FREEZE the template:

    \c template1

    VACUUM FREEZE;
