Could use per-table SQL expressions with sub-queries to pull + in small tables ("partial transform") and export JSON for each table; would + be extra work to maintain, so not pursuing for now. +- full history, full public schema exports, in a form that might be used to + mirror or enitrely fork the project. Propose supplying the full "changelog" + in API schema format, in a single file to capture all entity history, without + "hydrating" any inter-entity references. Rely on separate dumps of + non-entity, non-versioned tables (editors, abstracts, etc). Note that a + variant of this could use the public interface, in particular to do + incremental updates (though that wouldn't capture schema changes). +- transformed exports of the current state of the database (aka, without + history). Useful for data analysis, search engines, etc. Propose supplying + just the Release table in a fully "hydrated" state to start. Unclear if + should be on a work or release basis; will go with release for now. Harder to + do using public interface because of the need for transaction locking. + +## Full Postgres Backup + +Backing up the entire database using `pg_dump`, with parallelism 1 (use more on +larger machine with fast disks; try 4 or 8?), assuming the database name is +'fatcat', and the current user has access: + + pg_dump -j1 -Fd -f test-dump fatcat + +## Identifier Dumps + +The `extras/quick_dump.sql` script will dump abstracts and identifiers as TSV +files to `/tmp/`.
