You will get PostgreSQL database recovery when your cluster will not start
Project details
PostgreSQL database recovery for a cluster that will not start because of FATAL or PANIC errors, invalid checkpoints, WAL failures, control-file problems, damaged catalogs, missing relation files or storage I/O errors. I also recover dropped databases, schemas and tables; accidental TRUNCATE, DELETE or UPDATE data; and readable records from corrupted PGDATA or data files.
I preserve the source and reproduce the failure on a protected working copy. The safest result may be extracting usable data into a clean PostgreSQL cluster rather than forcing a damaged source to start. Depending on the evidence, I analyze startup logs, control data, WAL timelines, catalogs, relation files, page structure and TOAST.
Deliverables may include SQL, COPY or CSV, recovered object definitions, validation results and a technical report. Do not run pg_resetwal or initialize a replacement cluster on the only copy before assessment.
Authorized systems only.

About Tyler
PostgreSQL Data Recovery Specialist | Corruption, WAL, DROP & PGDATA
Nanjing, China - 1:19 pm local time
My work covers dropped databases, schemas and tables; accidental TRUNCATE, DELETE and UPDATE operations; clusters that fail with FATAL, PANIC, checkpoint or WAL errors; and corrupted PGDATA, relation files, 8KB pages, TOAST values and checksums.
I preserve the original evidence and work from a protected copy whenever possible. Depending on the incident, I analyze heap pages, MVCC tuple remnants, WAL, system catalogs, relation forks, page headers, TOAST references and known DDL. Recoverable records can be delivered as SQL, COPY or CSV with validation notes and a concise technical report.
Recent anonymized client work includes:
• 2,906,414 PostgreSQL 12 rows recovered after TRUNCATE with zero scan failures
• Three of four business-critical tables recovered after ransomware damage
• A 1.5TB PostgreSQL 16.7 and PostGIS 3.2.8 cluster extracted and restored after catalog corruption
Recovery is evidence-dependent and best-effort. Later writes, VACUUM, file reuse, missing WAL and physical media damage can reduce what remains recoverable. I handle only systems and data the client owns or is authorized to administer.
Steps for completing your project
After purchasing the project, send requirements so Tyler can start the project.
Delivery time starts when Tyler receives requirements from you.
Tyler works on your project following the steps below.
Revisions may occur after the delivery date.
Preserve and review the cluster evidence
Work from a protected copy and record versions, logs, storage state and the failure timeline.
Reproduce the startup failure
Reproduce the failure in an isolated environment without changing the original evidence.
