Updata to use DuckDB v1.0.0

[eydunn]

I built it with docker build and ran it in Docker Desktop.

create extension duckdb_fdw;

CREATE SERVER duckdb_server
FOREIGN DATA WRAPPER duckdb_fdw
OPTIONS (database '/tmp/duck.db');

SELECT duckdb_execute('duckdb_server','CREATE TABLE t1_duckdb (a integer, b text);');

CREATE FOREIGN TABLE t1 (
   a integer,
   b text
)
SERVER duckdb_server
OPTIONS (
    table 't1_duckdb'
);

select * from t1; 

insert into t1 values (1,'a');

select * from t1; 

SELECT duckdb_execute('duckdb_server','CREATE TABLE info_ddb as select version() as version;');
CREATE FOREIGN TABLE info_ddb (
   version text
)
SERVER duckdb_server
OPTIONS (
    table 'info_ddb'
);
select version as duckdb_version, duckdb_fdw_version() as duckdb_fdw_version, version() as postgrsql_version from info_ddb;

duckdb_version:
v1.0.0 

duckdb_fdw_version: 
20101

postgrsql_version:
PostgreSQL 16.3 (Debian 16.3-1.pgdg120+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 12.2.0-14) 12.2.0, 64-bit
