sbailliez / compress.sql
Created June 1, 2024 19:11
dbt macro (redshift only) to compress a specified set of columns
{#
Compresses the columns of a table to the specified encodings. Unlike the compress_table macro in dbt-redshift,
you have to manually specify the encoding of the columns you want to compress, it does not run and use
the result of `ANALYZE compression <table>` which would is extremely slow to run every time
on a large table, especially when there is nothing to do and the table is already compressed.
If the specified column does not exist or if the specified encoding is identical to the current encoding,
the column is skipped.
ALTER statements are generated for each column where encoding needs to be changed.

Upgrading from Postgresql 10.6 to Postgresql 11.1

Spent a few hours dealing with errors on RDS when upgrading from a postgresql 10.6 to 11.1. In case someone else is dealing with the same problems, this might be helpful.

A few things to know about this database:

  • PostGIS extension was installed but was not being used
  • ip4r extension was installed but was also not used

This probably turned out to be a Good Thing (tm). If you are using PostGIS extensively, I wish you good luck.
