This update includes a redefinition of <quote>daylight savings</quote>

in Ireland, as well as for some past years in Namibia and

Czechoslovakia. In those jurisdictions, legally standard time is

observed in summer, and daylight savings time in winter, so that the
|
||||
daylight savings offset is one hour behind standard time not one hour
|
||||
ahead. This does not affect either the actual UTC offset or the
|
||||
timezone abbreviations in use; the only known effect is that
|

the <structfield>is_dst</structfield> column in
|

the <structname>pg_timezone_names</structname> view will now be true
|
||||
in winter and false in summer in these cases.

Overoptimistic caching rules could prevent these updates from being

corruption. The problem was significantly worse for shared catalogs,

such as <structname>pg_authid</structname>, because the stale cache
|

data could persist into new sessions as well as existing ones.
