While running the command: sh sqlite-utils index-foreign-keys $SQLITE_DIR/pudl.sqlite

I got the following error:

Traceback (most recent call last): File "/home/zane/miniconda3/envs/pudl-dev/bin/sqlite-utils", line 8, in <module> sys.exit(cli()) File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/click/core.py", line 829, in __call__ return self.main(*args, **kwargs) File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/click/core.py", line 782, in main rv = self.invoke(ctx) File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/click/core.py", line 1259, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/click/core.py", line 1066, in invoke return ctx.invoke(self.callback, **ctx.params) File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/click/core.py", line 610, in invoke return callback(*args, **kwargs) File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/sqlite_utils/cli.py", line 454, in index_foreign_keys db.index_foreign_keys() File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/sqlite_utils/db.py", line 902, in index_foreign_keys table.create_index([fk.column]) File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/sqlite_utils/db.py", line 1563, in create_index self.db.execute(sql) File "/home/zane/miniconda3/envs/pudl-dev/lib/python3.9/site-packages/sqlite_utils/db.py", line 421, in execute return self.conn.execute(sql) sqlite3.OperationalError: index idx_generators_eia860_report_date already exists

This DB was created with the foreign key constraint PRAGMA enabled and a bunch of column-level CHECK constraints. Is this an expected behavior? Should one not try to index foreign keys if FK constraints are already being enforced within the DB?

I'm also noticing that the size of the DB after FK indexes have been added went from 483MB to 835MB, which seems like a much bigger jump than when I've done this previously.

Software versions... * sqlite-utils 3.17.1 * sqlite 3.36.0 * SQLAlchemy 1.4.26 (used to create the DB)
