*
* Modifications - 6 / 10 / 96 - dave @ bensoft . com - version 1.13 . dhb
*
* Applied ' insert string ' patch from " Marc G. Fournier " < scrappy @ ki . net >
* Added ' - t table ' option
* Added ' - a ' option
* Added ' - da ' option
*
* Modifications - 6 / 12 / 96 - dave @ bensoft . com - version 1.13 . dhb .2
*
* - Fixed dumpTable output to output lengths for char and varchar types !
* - Added single . quote to twin single quote expansion for ' insert ' string
* mode .
*
* Modifications - 7 / 26 / 96 - asussman @ vidya . com
*
* - Fixed ouput lengths for char and varchar type where the length is variable ( - 1 )
*
* Modifications - 6 / 1 / 97 - igor @ sba . miami . edu
* - Added functions to free allocated memory used for retrieving
* indexes , tables , inheritance , types , functions and aggregates .
* No more leaks reported by Purify .
*
*
* Modifications - 1 / 26 / 98 - pjlobo @ euitt . upm . es
* - Added support for password authentication
*
* Modifications - 28 - Jun - 2000 - Philip Warner pjw @ rhyme . com . au
* - Used custom IO routines to allow for more
* output formats and simple rearrangement of order .
* - Discouraged operations more appropriate to the ' restore '
* operation . ( eg . - c " clear schema " - now always dumps
* commands , but pg_restore can be told not to output them ) .
* - Added RI warnings to the ' as insert strings ' output mode
* - Added a small number of comments
* - Added a - Z option for compression level on compressed formats
* - Restored ' - f ' in usage output
*
*
* Modifications - 17 - Jul - 2000 - Philip Warner pjw @ rhyme . com . au
* - Support for BLOB output .
* - Sort archive by OID , put some items at end ( out of OID order )
*
* Modifications - 28 - Jul - 2000 - pjw @ rhyme . com . au ( 1.45 )
*
* Added - - create , - - no - owner , - - superuser , - - no - reconnect ( pg_dump & pg_restore )
* Added code to dump ' Create Schema ' statement ( pg_dump )
* Don ' t bother to disable / enable triggers if we don ' t have a superuser ( pg_restore )
* Cleaned up code for reconnecting to database .
* Force a reconnect as superuser before enabling / disabling triggers .
*
* Modifications - 31 - Jul - 2000 - pjw @ rhyme . com . au ( 1.46 , 1.47 )
* Added & Removed - - throttle ( pg_dump )
* Fixed minor bug in language dumping code : expbuffres were not being reset .
* Fixed version number initialization in _allocAH ( pg_backup_archiver . c )
*
* Modifications - 14 - Sep - 2000 - pjw @ rhyme . com . au
* Use symbols for tests on relkind ( ie . use RELKIND_VIEW , not ' v ' )
* Support for relkind = RELKIND_VIEW .
* Fix bug in support for - b option ( = = - - blobs ) .
* Dump views as views ( using ' create view ' ) .
* Remove ' isViewRule ' since we check the relkind when getting tables .
* Now uses temp table ' pgdump_oid ' rather than ' pg_dump_oid ' ( errors otherwise ) .
*
* Modifications - 02 - Oct - 2000 - pjw @ rhyme . com . au
*
* - Be more paranoid when getting views : call get_viewdef in separate statement
* so we can be more informative in error messages .
* - Support for ' isstrict ' procedure attribute .
* - Disable - - blobs and - - table since ( a ) it ' s a pain to get ONLY the blobs for the
* table with the currently implementation , and ( b ) it ' s not clear how to restore
* a partial BLOB backup ( given the current OID - based BLOB implementation ) .
*
* Modifications - 04 - Jan - 2001 - pjw @ rhyme . com . au
*
* - Check ntuples = = 1 for various SELECT statements .
* - Fix handling of - - tables = * ( multiple tables never worked properly , AFAICT )
*
* Modifications - 13 - Feb - 2001 - pjw @ rhyme . com . au
*
* - Fix help output : replace ' f ' with ' t ' and change desc .
* - Add extra arg to formatStringLiteral to specify how to handle LF & TAB .
* I opted for encoding them except in procedure bodies .
* - Dump relevant parts of sequences only when doing schemaOnly & dataOnly
* - Prevent double - dumping of sequences when dataOnly .
*
* Modifications - 19 - Mar - 2001 - pjw @ rhyme . com . au
*
* - Remove fmtId calls for all ArchiveEntry name fields . This fixes
* quoting problems in trigger enable / disable code for mixed case
* table names , and avoids commands like ' pg_restore - t ' " TblA " ' '
*
* Modifications - 31 - Mar - 2001 - pjw @ rhyme . com . au
*
* - Dump dependency information in dumpType . This is necessary
* because placeholder types will have an OID less than the
* OID of the type functions , but type must be created after
* the functions .
*
* Modifications - 4 - Apr - 2001 - pjw @ rhyme . com . au
*
* - Don ' t dump CHECK constraints with same source and names both
* starting with ' $ ' .
*
* Modifications - 10 - May - 2001 - pjw @ rhyme . com . au
*
* - Don ' t dump COMMENTs in data - only dumps
* - Fix view dumping SQL for V7 .0
* - Fix bug when getting view oid with long view names
