|

* routines to convert a node to ascii representation

*
|
|
* NOTES
|
|
* Every (plan) node in POSTGRES has an associated "out" routine which
|
|
* knows how to create its ascii representation. These functions are
|
|
* useful for debugging as well as for storing plans in the system
|
|
* catalogs (eg. indexes). This is also the plan string sent out in
|
|
* Mariposa.
|
|
*
|
|
* These functions update the in/out argument of type StringInfo
|
|
* passed to them. This argument contains the string holding the ASCII
|
|
* representation plus some other information (string length, etc.)
|
