* fix: Use get_index() instead of list_indexes() in has_collection() to handle pagination
Fixes#19233
Replace list_indexes() pagination scan with direct get_index() lookup
in has_collection() method. The previous implementation only checked
the first ~1,000 indexes due to unhandled pagination, causing RAG
queries to fail for indexes beyond the first page.
Benefits:
- Handles buckets with any number of indexes (no pagination needed)
- ~8x faster (0.19s vs 1.53s in testing)
- Proper exception handling for ResourceNotFoundException
- Scales to millions of indexes
* Update s3vector.py
Unneeded exception handling removed to match original OWUI code
* Adding hnsw index type for pgvector, allowing vector dimensions larger than 2000
* remove some variable assignments
* Make USE_HALFVEC variable configurable
* Simplify USE_HALFVEC handling
* Raise runtime error if the index requires rebuilt

This commit introduces support for the DISKANN index type in the Milvus vector database integration.
Changes include:
- Added `MILVUS_DISKANN_MAX_DEGREE` and `MILVUS_DISKANN_SEARCH_LIST_SIZE` configuration variables.
- Updated the Milvus client to recognize and configure the DISKANN index type during collection creation.
The pymilvus library expects -1 for unlimited queries, but the code was passing None, which caused a TypeError. This commit changes the default value of the limit parameter in the query method from None to -1. It also updates the call site in the get method to pass -1 instead of None and updates the type hint and a comment to reflect this change.
Replace direct CREATE EXTENSION commands with conditional checks to avoid
permission errors on Azure PostgreSQL Flexible Server where only
azure_pg_admin members can create extensions.
- Check pg_extension table before attempting to create vector extension
- Apply same fix to pgcrypto extension for consistency
- Allows following least privilege principle for database users
Fixes#12453
