Postgres Operator vs Stirling-PDF: at a glance
What is Postgres Operator?
Postgres Operator v2.0.3 makes md5 pooler auth opt-in in a bug-fix release.
Zalando's Postgres Operator shipped v2 in late July with Postgres 18 support, EKS IRSA and an ARM pooler, then needed two cleanup releases. v2.0.3 on October 2 fixes primary-pod migration retries, avoids needless switchovers on single-pod clusters and passes AWS regions under IRSA. It also changes behaviour: pooler connections relying on md5 auth now need password_encryption: md5 set explicitly.
What is Stirling-PDF?
Stirling PDF's 3.x line ships bulk processing, org-wide signing and fortnightly feature releases
Stirling PDF 3.0 in late September added the PDF Processor for running tools across folders, FTP or S3 sources, optional AI classification and extraction, free OAuth SSO and a free allowance of 1,000 automated PDFs a month. Releases since have arrived about every two weeks: 3.1.0 made group signing (Stirling Sign) default for new users and trialled an embedded Office converter, 3.2.0 replaced the multi-tool with a Page Editor and let password-protected PDFs be used without removing the password, and 3.2.1 and 3.2.2 added viewer and annotation features.

Postgres Operator
0.0DEVOPS
Postgres Operator v2.0.3 makes md5 pooler auth opt-in in a bug-fix release.
◆ Current state
Zalando's Postgres Operator shipped v2 in late July with Postgres 18 support, EKS IRSA and an ARM pooler, then needed two cleanup releases. v2.0.3 on October 2 fixes primary-pod migration retries, avoids needless switchovers on single-pod clusters and passes AWS regions under IRSA. It also changes behaviour: pooler connections relying on md5 auth now need password_encryption: md5 set explicitly.
◆ Where it's heading
The v2 line is still in stabilization, with each patch carrying a breaking change of some kind. The AWS and IRSA fixes suggest EKS users are the main early adopters.
◆ Prediction
Expect further 2.0.x patches on a roughly six-week cycle; a 2.1 feature release is not visible in the entries.
Stirling-PDF
5.0DEVOPS
Stirling PDF's 3.x line ships bulk processing, org-wide signing and fortnightly feature releases
◆ Current state
Stirling PDF 3.0 in late September added the PDF Processor for running tools across folders, FTP or S3 sources, optional AI classification and extraction, free OAuth SSO and a free allowance of 1,000 automated PDFs a month. Releases since have arrived about every two weeks: 3.1.0 made group signing (Stirling Sign) default for new users and trialled an embedded Office converter, 3.2.0 replaced the multi-tool with a Page Editor and let password-protected PDFs be used without removing the password, and 3.2.1 and 3.2.2 added viewer and annotation features.
◆ Where it's heading
The product is moving from a self-hosted toolbox to an automation and workflow platform with metered hosted services attached. Feature releases come quickly, with visible regressions fixed in the next point release.
◆ Prediction
Expect Stirling Office Convert to move toward default and native desktop, as the 3.1.0 notes say is planned, plus continued Processor work.
