cannot to load pg_ducklake

[okbob]

I compiled pg_ducklake against PostgreSQL 18, but I cannot to use it, because there is undefined symbol

/usr/local/pgsql/18/lib/pg_ducklake.so: undefined symbol: _ZN8pgduckdb21GetPostgresDuckDBTypeERKN6duckdb11LogicalTypeEb

Currently we have some customization on pg_duckdb, so it does not work with upstream pg_duckdb yet. Instead you should build and install pg_duckdb from our repo. We're working hard to stabilize our ABI and upstream our changes to pg_duckdb.
