The following section
http://www.ca.postgresql.org/devel-corner/docs/postgres/locking-tables.html
titled "Locking and Tables", has two subsections, "Table-level locks" and
"Row-level locks". Under table-level locks we find lock names such as
RowShareLock and RowExclusiveLock -- are those table-level locks? Under
row-level locks we find no specific lock names mentioned.
What I wonder is, if I do
BEGIN;
LOCK table1 IN ROW EXCLUSIVE MODE;
what do I lock? The table? A row? Which row?
Clarification appreciated.
