The release also fixes long-standing deployment pain points by distributing psycopg2 as a self-contained wheel on PyPI, so installing it no longer requires a C compiler, headers, pg_config, or libpq. The stable release is expected the following week pending testing feedback, with beta packages available on the PyPI testing site. ## Full article daily.dev links to this article rather than hosting it.

Psycopg2 2.7 beta 2 adds support for the PostgreSQL replication protocol, along with helpers to dynamically build SQL statements and manipulate connection strings, speedups in multiple execution and Unicode decoding, and better transaction handling. It arrived roughly two years after the prior major release. _Track library updates like psycopg2's replication support as you plan database upgrades on daily.dev._ ### Do I still need a C compiler and libpq installed to pip install psycopg2? No, starting with psycopg2 2.7 beta 2, the package is distributed as a self-contained wheel on PyPI, so running pip install psycopg2 no longer requires a C compiler, headers, pg_config, or libpq to be present, fixing a common deployment problem for Windows and OSX users. _daily.dev helps developers stay ahead of packaging changes that simplify dependencies like psycopg2._ --- Tags: [#python](https://daily.dev/tags/python), [#postgresql](https://daily.dev/tags/postgresql) [View this post on daily.dev](https://daily.dev/posts/postgresql-adapter-for-python-jbkaa4grl) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"PostgreSQL adapter for Python","url":"https://daily.dev/posts/postgresql-adapter-for-python-jbkaa4grl","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/postgresql-adapter-for-python-jbkaa4grl"},"datePublished":"2026-08-23T12:18:56.306Z","dateModified":"2026-08-23T12:30:04.193Z","description":"Psycopg2 2.7 beta 2 has been released, bringing replication protocol support, helpers for dynamically building SQL statements and manipulating connection...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b0cbd2ac8948f96ab39fa6a90db7464f?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b0cbd2ac8948f96ab39fa6a90db7464f?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Psycopg","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Psycopg","logo":"https://media.daily.dev/image/upload/s--5N-KNNWk--/f_auto,q_auto/v1787487485/logos/psycopg?_a=BAMAMicg0","url":"https://daily.dev/sources/psycopg"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/postgresql-adapter-for-python-jbkaa4grl","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"python,postgresql","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Psycopg","item":"https://daily.dev/sources/psycopg"},{"@type":"ListItem","position":3,"name":"PostgreSQL adapter for Python"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/postgresql-adapter-for-python-jbkaa4grl#faq","mainEntity":[{"@type":"Question","name":"What's new in psycopg2 2.7 for PostgreSQL replication support?","acceptedAnswer":{"@type":"Answer","text":"Psycopg2 2.7 beta 2 adds support for the PostgreSQL replication protocol, along with helpers to dynamically build SQL statements and manipulate connection strings, speedups in multiple execution and Unicode decoding, and better transaction handling.
