Single file PHP script that adds a REST API to a MySQL/MariaDB, PostgreSQL, SQL Server or SQLite database.
POSTGRESQL 12 64-BIT FOR WINDOWS FDWS
odbc_fdw (version 0.4.0) for connecting to ODBC data sources such as SQL Server, Oracle, MS Access databases, and anything else that has a 64-bit ODBC driver. Note that since this is for PostgreSQL 64-bit, it can only use ODBC 64-bit connections.
file_textarray_fdw, great and fast for working with arbitrary and pesky delimited data. Especially where they weren't considerate enough to give you the same number of columns per row.
