Broken pinecone-client dependency in pinecone-haystack

[askainet]

Describe the bug

Pinecone renamed their official SDK package from pinecone-client to pinecone after releasing v5.0.1 on 2024-08-01, and since then v5.1, v5.2, v5.3, and v5.4 were published only in pinecone (pinecone package history).

On 2025-02-21, Pinecone published a breaking v6.0.0 in the deprecated "pinecone-client" package, which throws an exception on import to warn users about the package rename.

The pinecone-haystack integration requires pinecone-client>=3, which installs the broken v6.0.0 currently.

To Reproduce

Since 2025-02-21, the broken pinecone-client==6.0.0 requirement is installed:

; project_dir="$(mktemp -d)" sh -x <<'EOF'
  cd "${project_dir}"
  uv venv -q
  uv pip -q install "pinecone-haystack"
  uv pip freeze | grep pinecone
  uv run python -c "from haystack_integrations.document_stores.pinecone import PineconeDocumentStore; print(PineconeDocumentStore.__doc__);"
EOF

pinecone-client==6.0.0
pinecone-haystack==3.0.0
pinecone-plugin-interface==0.0.7
