  1. This commit adds support for temporary files compression, it can be u… 

    …sed only for hashjoins now.

It also adds GUC parameter temp_file_compression that enables this functionality.
For now, it supports just lz4 and pglz algorithms. In the future, it
could also be implemented zstd support.

It implements just one working buffer for compression and decompression to avoid
memory wasting. The buffer is allocated in the top memory context.
