Hello! I have stable Discourse 2.4.1 with external PostgreSQL 9.5.23.
I trying upgrade to stable 2.5.1 and received error wit
bundle rake dm:migration step:
PG::SyntaxError: ERROR: syntax error at or near "NOT" LINE 2: ADD COLUMN IF NOT EXISTS image_upload_id bigint
Is it because PostgreSQL is very old? Which PostgreSQL version is recommended?
