Pulumi fork carrying MeltanoLabs/tap-postgres#772 (single-pass WAL reader for LOG_BASED replication) ahead of its upstream merge.
Why: stock tap-postgres opens one replication connection per stream sharing a single slot and advances the slot to the WAL tip per-stream, so a bulk multi-table transaction lets one table's stream advance the shared slot past another table's un-consumed WAL → silent data loss. MeltanoLabs#772 drains the WAL once across all selected tables in LSN order so they advance together.

pulumi/dwh-workflows(Burrow CDC) pinned at tagv0.9.0(this branch's head), withlog_based_single_connection: true. Local meltano build validated: installs clean, version resolves to0.9.0.Drop this fork and pin a released meltanolabs version once MeltanoLabs#772 merges upstream.
