Avoid resource leak (src/bin/pg_dump/pg_dumpall.c)

[Ranier Vilela]

Hi.

Per Coverity.

Coverity complains about one resource leak in the function
*drops_DBs*.

CID 1645454: (#1 of 1): Resource leak (RESOURCE_LEAK)
19. leaked_storage: Variable delQry going out of scope leaks the storage it
points to.

Fix by avoiding creating the buffer unnecessarily.

Trivial patch attached.

best regards,
Ranier Vilela
