I'm trying to install postgres vector extension on my mac but am getting ERROR: extension "vector" has no installation script nor update path for version "0.4.0". Here's what I did: Follow the installation guide as shown on github: But when I ran CREATE EXTENSION vector; got an err...
This repository makes it easy to deploy a PostgreSQL Flexible Server to Azure with the pgvector extension installed. The pgvector extension provides a vector similarity search engine for PostgreSQL, allowing you to perform similarity searches on your data using vector embeddings....
However, this can lead to Illegal instruction errors if trying to run the compiled extension on a different machine.To compile for portability, use:make OPTFLAGS=""Installation Notes - WindowsMissing HeaderIf compilation fails with Cannot open include file: 'postgres.h': No such file or ...
