I am trying to install an extension to postgres that will help me write postgres queries to read data directly from parquet files. This is the extension I found - https://github.com/pgspider/parquet_s3_fdw

After installing the required dependencies I went ahead and tried running the 'make' command.

make install

But ends up with an error

Makefile:45: /contrib/contrib-global.mk: No such file or directory
make: *** No rule to make target '/contrib/contrib-global.mk'.  Stop.

Has anyone else tried using this extension ? Or can you suggest me some other way to read data directly from parquet files while using postgres ? (Please note: conversion from parquet to any other format is not allowed under the circumstances that I'm trying this)

Thanks

I'm not sure about the error there but the FDW you referenced is for accessing parquet files on S3 which you didn't mention as a requirement. You might want to try a simpler version like https://github.com/adjust/parquet_fdw

For reference see the answers to Patel's question here: https://github.com/pgspider/parquet_s3_fdw/issues/7

Long story short, the solution is to append USE_PGXS=1 to the make install command:

$ make install USE_PGXS=1
