What is relation 266775 of database 196511? Is
it cms_c207c1e2_0ce7_422c_aafb_77d43f61e563.cms_item or some system catalog
table?
When I search google for "ExclusiveLock on extension of relation" I find
one thread about shared_buffers being very high but not big enough to fit
the entire data in the cluster. How much ram, what is shared buffers and
what is the total size of the database(s) on that Postgres instance?
