## Problem Introducing pg_duckdb caused a conflict with pg_mooncake. Both use libduckdb.so in different versions. ## Summary of changes - Rename the libduckdb.so to libduckdb_pg_duckdb.so in the context of pg_duckdb so that it doesn't conflict with libduckdb.so referenced by pg_mooncake. - use a version map to rename the duckdb symbols to a version specific name - DUCKDB_1.1.3 for pg_mooncake - DUCKDB_1.2.0 for pg_duckdb For the concept of version maps see - https://www.man7.org/conf/lca2006/shared_libraries/slide19a.html - https://peeterjoot.com/2019/09/20/an-example-of-linux-glibc-symbol-versioning/ - https://akkadia.org/drepper/dsohowto.pdf
This directory contains files that are needed to build the compute images, or included in the compute images.
compute-node.Dockerfile To build the compute image
vm-image-spec.yaml Instructions for vm-builder, to turn the compute-node image into corresponding vm-compute-node image.
etc/ Configuration files included in /etc in the compute image
patches/ Some extensions need to be patched to work with Neon. This directory contains such patches. They are applied to the extension sources in compute-node.Dockerfile
In addition to these, postgres itself, the neon postgres extension, and compute_ctl are built and copied into the compute image by compute-node.Dockerfile.
