Overview

A quick release to improve postgres support.

Changes

Support TLS in Postgres Connections
Compiler Version Requirements

Upgrade Notes

There's no significant changes from 0.5.1, so upgrading should be as simple as pulling a new version of pict-rs.

Descriptions

Support TLS in Postgres Connections

The postgres repo now supports some new options to enable connecting via TLS. If the postgres server's certificate is not generally trusted, a CA certificate can be provided to pict-rs to allow it to trust the postgres connection.

If the postgres endpoint uses TLS and has a publicly trusted certificate, the configuration can be updated to simply add use_tls = true

[repo]
type = 'postgres'
url = 'postgres://pictrs:1234@localhost:5432/pictrs'
use_tls = true

or with environment variables

PICTRS__REPO__TYPE=postgres
PICTRS__REPO__URL=postgres://pictrs:1234@localhost:5432/pictrs
PICTRS__REPO__USE_TLS=true

If the server uses a self-signed certificate, the CA's certificate can be added to pict-rs' trusted CAs.

[repo]
type = 'postgres'
url = 'postgres://pictrs:1234@localhost:5432/pictrs'
use_tls = true
certificate_file = '/path/to/ca/certificate.crt'

or with environment variables

PICTRS__REPO__TYPE=postgres
PICTRS__REPO__URL=postgres://pictrs:1234@localhost:5432/pictrs
PICTRS__REPO__USE_TLS=true
PICTRS__REPO__CERTIFICATE_FILE=/path/to/ca/certificate.crt

Compiler Version Requirements

pict-rs 0.5.2 now takes advantage of rust's native support for AFIT (Async Fn In Trait) for the store trait. This trait already was not object-safe, so using AFIT does not come with any downsides. This does mean that the minimum supported rust version for building pict-rs is now 1.75, which released in December 2023.
