Install Gaia DR2 Catalogue at Subaru

Following discussions in the last ICS/PFI telecon (https://sumire.pbworks.com/w/page/141309765/ICS-PFI-MCS%20telecon%20on%20Sep%2018%202020) we should have a local installation of the Gaia DR2 catalogue at Subaru. This would be a useful for guide stars, for fiber allocation software (FIBERALLOC-33) etc.

Having a local copy would preclude problems accessing guide stars due to external network issues.

The catalogue should be queryable, so ingested into a postgres or equivalent database instance.

The size of the Gaia DR2 in CSV format is 550 GB. If the size is an issue, it may be possible to store a only subset of fields. But this needs to be discussed further.
