44.11. PL/Tcl Configuration

+ This section lists configuration parameters that + affect PL/Tcl. +

+ pltcl.start_proc (string) + +

+ This parameter, if set to a nonempty string, specifies the name + (possibly schema-qualified) of a parameterless PL/Tcl function that + is to be executed whenever a new Tcl interpreter is created for + PL/Tcl. Such a function can perform per-session initialization, such + as loading additional Tcl code. A new Tcl interpreter is created + when a PL/Tcl function is first executed in a database session, or + when an additional interpreter has to be created because a PL/Tcl + function is called by a new SQL role. +

+ The referenced function must be written in the pltcl + language, and must not be marked SECURITY DEFINER. + (These restrictions ensure that it runs in the interpreter it's + supposed to initialize.) The current user must have permission to + call it, too. +

+ If the function fails with an error it will abort the function call + that caused the new interpreter to be created and propagate out to + the calling query, causing the current transaction or subtransaction + to be aborted. Any actions already done within Tcl won't be undone; + however, that interpreter won't be used again. If the language is + used again the initialization will be attempted again within a fresh + Tcl interpreter. +

+ Only superusers can change this setting. Although this setting + can be changed within a session, such changes will not affect Tcl + interpreters that have already been created. +

+ pltclu.start_proc (string) + +

+ This parameter is exactly like pltcl.start_proc, + except that it applies to PL/TclU. The referenced function must + be written in the pltclu language. +
