Virtualbox

Running linux as a non root user in virtualbox. To mount VirtualBox shared folder on Linux and access everything within the shared folder as the user, in this example htpcbeginner, you will have to manually add the user to vboxsf group...then log out and log in.

PostgresSql option for creating table like another table


In MSSQL there is an easy, code-based, way to create a table with the same DDL and data as another table.
This is simply by running a query similar to this:



select * INTO "NEW TABLE" FROM "SOURCE TABLE"

I needed to do something similar in PostgreSQL and found this to be a nice way to recreate a table using another as a templet

CREATE TABLE TESTTABLE
AS
  SELECT *
  FROM "SOURCE TABLE"
  WHERE false;

psycopg2 on MacOS


I have recently been having some issues with install the python module psycopg2 on a mac os Mojave. No matter what modules I installed in the virtual environment, the pip install of psycopg2 would not find a suitable candidate.

I tried all sorts of ways to get around this, like installing the entire Postgresql engine via brew, all to no avail.

Eventually, I found this pip module (which I should have found earlier to be honest if I had been more attentive :) )

pip install psycopg2-binary
