He is Little Rock 's District Engineering Division Technical Manager for the Montgomery Point project . Thus , the rule system caused one extra scan on the shoelace_data relation that is absolutely not necessary . So , basically , we no longer are restricted by simple table-level locking ; we have something better than row-level locking . Although the minimum required memory for running Postgres is as little as 8MB , there are noticable improvements in runtimes for the regression tests when expanding memory up to 96MB on a relatively fast dual-processor system running X-Windows . The little red hen was now stable financially . Postgres is also unlike most other data managers in that the server can incorporate user-written code into itself through dynamic loading . He does this to ensure the existing pipes are capable of supporting the extra forces and pressure created by the Uprate Program designed to allow nuclear power plants to produce more power with existing equipment . In Postgres 6.4 and later , it is possible to avoid such extra work by noticing whether the notifying backend process 's PID ( supplied in the notify event message ) is the same as one 's own backend 's PID ( available from libpq ) . However , for a plain-vanilla first installation with no extra options like multi-byte character support or locale collation support it may be adequate to have chosen the installation areas and to run configure without extra options specified . As she left her class on economics , the little red hen had a spark of intuition . Suddenly the little red hen ’ s corporation was making millions , and the company ’ s stock soared . It takes the output of the parser , one querytree , and the rewrite rules from the pg_rewrite catalog , which are querytrees too with some extra information , and creates zero or many querytrees as result .
