Revision 12539

Added by Aaron Marcuse-Kubitza over 10 years ago

web/links/index.htm: updated to Firefox bookmarks: PostgreSQL: added links for error reporting levels and how to hide stack traces in psql. SQL: added links for recursive queries, which can be used to traverse hierarchical (parent-pointer) tables.

*** &quot;A common error is to label a function IMMUTABLE when its results depend on a configuration parameter. For example, a function that manipulates timestamps might well have results that depend on the TimeZone setting. For safety, such functions should be labeled STABLE instead.&quot;


  		




  840
  
  
    
this especially includes functions that depend on the search_path! (ie. that lack schema qualifiers on all invoked functions.) however, this effect will only be noticeable if the function is called on only *constant* values in a *PL/pgSQL* function, in which case the wrong search_path (the one in effect at *create* time) will be used.

** &quot;There is relatively little difference between STABLE and IMMUTABLE categories when considering simple interactive queries that are planned and immediately executed: it doesn&#39;t matter a lot whether a function is executed once during planning or once during query execution startup. But there is a big difference if the plan is saved and reused later. Labeling a function IMMUTABLE when it really isn&#39;t might allow it to be prematurely folded to a constant during planning, resulting in a stale value being re-used during subsequent uses of the plan. This is a hazard when using prepared statements or when using function languages that cache plans (such as PL/pgSQL).&quot;


  		




  843
  852
  
    
ie. if you are going to use your STABLE function in a PL/pgSQL function, be sure to label it STABLE so that it does not get constant-folded until call time (if labeled IMMUTABLE, it would be folded right away when the function is created)

<DD>&quot;For some types of errors, the server reports the name of a database object (a table, table column, data type, or constraint) associated with the error; for example, the name of the unique constraint that caused a unique_violation error. Such names are supplied in separate fields of the error report message so that applications need not try to extract them from the possibly-localized human-readable text of the message. As of PostgreSQL 9.3, complete coverage for this feature exists only for errors in SQLSTATE class 23 (integrity constraint violation), but this is likely to be expanded in future.&quot;


  		




  
  868
  
    
this is especially useful for error parsing in column-based import [wiki.vegpath.org/Column-based_import] (and may even have been motivated by it!)

<DD>&quot;pg_catalog is always effectively part of the search path. If it is not named explicitly in the path then it is implicitly searched before searching the path&#39;s schemas. This ensures that built-in names will always be findable. However, you can explicitly place pg_catalog at the end of your search path if you prefer to have user-defined names override built-in names.&quot;
