Is Plpgsql fast?
PL/pgSQL functions execute queries like prepared statements. Re-using cached query plans cuts off some planning overhead and makes them a bit faster than equivalent SQL statements, which may be a noticeable effect depending on circumstances.

Is PostgreSQL slow?
4.3. PostgreSQL attempts to do a lot of its work in memory, and spread out writing to disk to minimize bottlenecks, but on an overloaded system with heavy writing, it’s easily possible to see heavy reads and writes cause the whole system to slow as it catches up on the demands.
Should I use Postgres 13 or 14?
Already here we can see that Postgres 14 does much better in the initial data load. As you can see, the throughput of Postgres 14 at 5000 active connections is about 20% higher. At 10,000 active connections the improvement is 50% over Postgres 13, and at lower connection counts you can also see consistent improvements.
How make PostgreSQL query run faster?
To quickly review the join and scan types that PostgreSQL works with:
- Scan Types. Sequential Scan. Basically a brute-force retrieval from disk. Scans the whole table. Fast for small tables.
- Join Types. Nested Loops. For each row in the outer table, scan for matching rows in the inner table. Fast to start, best for small tables.
