I tried upgrading my postgres database and getting the following error:

pg$\_$dump: error: query failed: FATAL: terminating connection due to administrator command

server closed the connection unexpectedly

This probably means the server terminated abnormally

before or while processing the request.

pg$\_$dump: error: query was: SELECT t$.$tableoid, t$.$oid, t$.$relname AS indexname, $0$ AS parentidx, pg$\_$catalog.pg$\_$get$\_$indexdef$($i$.$indexrelid$)$ AS indexdef, i$.$indnatts AS indnkeyatts, i$.$indnatts AS indnatts, i$.$indkey, i$.$indisclustered, i$.$indisreplident, c$.$contype, c$.$conname, c$.$condeferrable, c$.$condeferred, c$.$tableoid AS contableoid, c$.$oid AS conoid, pg$\_$catalog.pg$\_$get$\_$constraintdef$($c$.$oid, false$)$ AS condef, $($SELECT spcname FROM pg$\_$catalog.pg$\_$tablespace s WHERE s$.$oid $=$ t$.$reltablespace$)$ AS tablespace, t$.$reloptions AS indreloptions, $\text{'}\text{'}$ AS indstatcols, $\text{'}\text{'}$ AS indstatvals FROM pg$\_$catalog.pg$\_$index i JOIN pg$\_$catalog.pg$\_$class t ON $($t$.$oid $=$ i$.$indexrelid$)$ LEFT JOIN pg$\_$catalog.pg$\_$constraint c ON $($i$.$indrelid $=$ c$.$conrelid AND i$.$indexrelid $=$ c$.$conindid AND c$.$contype IN $(\text{'}$p$\text{'},\text{'}$u$\text{'},\text{'}$x$\text{'}))$ WHERE i$.$indrelid $=\text{'}754949\text{'}$::pg$\_$catalog.oid AND i$.$indisvalid AND i$.$indisready ORDER BY indexname
