PostgreSQL Consulting in Exeter
PostgreSQL advice for Exeter organisations, where the most common slow decline has an unglamorous cause. Updates and deletes leave dead rows behind for a background process to reclaim, and on a busy table where that process cannot keep up, the table grows steadily larger than its data while queries get slower for no visible reason.
Why this comes up
The problem
A frequently updated table occupies far more space than its row count justifies, and queries against it have gradually slowed.
What you get
What we deliver
- Bloat measured per table rather than assumed absent
- Autovacuum tuned for the tables that need it instead of the global default
- Long-running transactions identified, since these prevent cleanup entirely
- Query plans examined at production data volumes, not at development scale
- Index usage reviewed, as unused indexes cost writes and disk for nothing
- Connection handling assessed, because the limit is lower than most teams expect

PostgreSQL Consulting in Exeter — common questions
- Why does the table grow beyond its data?
- Because an update writes a new row version and leaves the old one to be reclaimed later. Where the cleanup process is configured for a quiet table and applied to a busy one, dead rows accumulate faster than they are removed and the table steadily inflates.
- What stops the cleanup working?
- Usually a long-running transaction. Nothing newer than the oldest open transaction can be reclaimed, so a session left idle in a transaction — frequently an application bug or an analyst's forgotten window — blocks cleanup across the entire database.
- Why test plans at production volume?
- Because the planner chooses differently as data grows. A query using an index at ten thousand rows may switch to a sequential scan at ten million, and a development database with a small sample gives no warning that the plan will change under real conditions.
- Do unused indexes matter?
- They cost on every write and consume disk and memory. Databases accumulate indexes added for a query that changed years ago, and the statistics views show which have never been used — removing those makes writes faster at no cost to any query anyone runs.
- Do you work with businesses across Devon?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Exeter and the surrounding Devon area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Exeter businesses do you usually work with?
- Field service scheduling and routing for businesses covering a wide rural patch, plus professional services systems. Beyond that we work across Higher Education, Professional Services, Healthcare, Retail and Environmental Science.
- Do you cover the areas around Exeter?
- Yes — we work throughout South West, including Plymouth, Truro, Bristol. Exeter is an urban area of roughly 130,000+, and we take on work across the wider Devon region rather than the city boundary alone.
