Commit 5ab2c66

Rearrange dblink's dblink_build_sql_insert() and related routines to open and
lock the target relation just once per SQL function call. The original coding
obtained and released lock several times per call. Aside from saving a
not-insignificant number of cycles, this eliminates possible race conditions
if someone tries to modify the relation's schema concurrently. Also
centralize locking and permission-checking logic.
Problem noted while investigating a trouble report from Robert Voinea --- his
problem is still to be fixed, though.1 parent 6742c60 commit 5ab2c66
