BUG: ADBC Postgres writer incorrectly names the table

[LeonLuttenberger]

Pandas version checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pandas.

• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import adbc_driver_postgresql.dbapi as pg_dbapi
import pandas as pd

con = pg_dbapi.connect(uri="<PG_URI>")
table_name = "my_table"

df = pd.DataFrame({"c0": [1, 2, 3], "c1": ["foo", "boo", "bar"]})
df.to_sql(name=table_name, con=con, schema="public", if_exists="replace")

Issue Description

The table which ends up being created in the public schema ends up being named public.my_table, instead of just my_table. The table is then inaccessible, as the following code throws this error ValueError: Table my_table not found:

df_out = pd.read_sql_table(table, con, schema="public")

The created table can be found using the following code:

objects = con.adbc_get_objects(depth="tables", db_schema_filter="public", catalog_filter="postgres").read_all()
catalogs = objects.to_pylist()

all_tables = catalogs[0]["catalog_db_schemas"][0]["db_schema_tables"]
table = [x for x in all_tables if table in x["table_name"]][0]

Expected Behavior

Table gets created under the name specified, without including the schema name in the table name.
