Postgres got minor updates on Nov9, this starts using the images with
the latest version for our tests, namely 14.10, 15.5 and 16.1.
These minor updates were compatible with Citus.
Sister PR: https://github.com/citusdata/the-process/pull/152
When debugging postgres it is quite hard to get to the source for
`errfinish` in `elog.c`. Instead of relying on the developer to set a
breakpoint in the `elog.c` file for `errfinish` for `elevel == ERROR`,
this change adds the breakpoint to `.gdbinit`. This makes sure that
whenever a debugger is attached to a postgres backend it will break on
postgres errors.
When attaching the debugger a small banner is printed that explains how
to disable the breakpoint.
During the creation of the devcontainer we need to add a ppa repository,
which is easiest done via software-properies-common. As turns out this
installes pkexec into the container as a side effect.
When vscode tries to attach a debugger it first checks if pkexec is
installed as this gives a nicer popup asking for elevation of rights to
attach to the process. However, since dev containers don't have a
windowing system running pkexec isn't working as expected and thus
prevents the debugger from attaching.
Without pkexec in the container vscode 'falls back' to plain old sudo
which we can run passwordless in the container.
For pkexec to be removed we need to first purge
software-propertied-common as well as autoremove all packages that were
installed due to the installation of said package. By performing this
all in one step we minimize the size of the layer we are creating.
This change adds a devcontainer configuration to the Citus project. This
devcontainer allows for quick generation of isolated development
environments, either local on the machine of a developer or in a cloud,
like github codepaces.
The devcontainer is updated automatically by github actions when its
configuration changes.

container see CONTRIBUTING.md
