Hello everyone, I’m preparing an upgrade from Discourse 3.4.5 to 2026.1 and I noticed the migration 20251007123645_upgrade_pg_vector080_take2, which updates pgvector to 0.8.0 if needed. My question is: Would it be safe to manually upgrade pgvector to 0.8.0 in the current database before running t…

Yes, that is safe. And it is common scenario for people running in hosted PostgreSQL services.

هل الترقية إلى pgvector 0.8.0 آمنة قبل تشغيل الترحيل 20251007123645؟

نعم، هذا آمن. وهو سيناريو شائع للأشخاص الذين يعملون في خدمات PostgreSQL المستضافة.
