yes, lot of is regress tests (expected part is 3x) - and XMLTABLE function is not trivial. lot of code is mechanical - nodes related. The really complex part is only in xml.c. There is one longer function only - the complexity is based on mapping libxml2 result to PostgreSQL result (with catching exceptions due releasing libxml2 sources). The all changes are well isolated - there is less risk to break some other. > > doc/src/sgml/func.sgml | 376 ++++++++++++++++++--- > src/backend/executor/execQual.c | 335 +++++++++++++++++++ > src/backend/executor/execTuples.c | 42 +++ > src/backend/nodes/copyfuncs.c | 66 ++++ > src/backend/nodes/equalfuncs.c | 51 +++ > src/backend/nodes/nodeFuncs.c | 100 ++++++ > src/backend/nodes/outfuncs.c | 51 +++ > src/backend/nodes/readfuncs.c | 42 +++ > src/backend/optimizer/util/clauses.c | 33 ++ > src/backend/parser/gram.y | 181 ++++++++++- > src/backend/parser/parse_coerce.c | 33 +- > src/backend/parser/parse_expr.c | 182 +++++++++++ > src/backend/parser/parse_target.c | 7 + > src/backend/utils/adt/Makefile | 2 +- > src/backend/utils/adt/ruleutils.c | 100 ++++++ > src/backend/utils/adt/xml.c | 610 ++++++++++++++++++++++++++++++ > +++++ > src/backend/utils/adt/xpath_parser.c | 337 +++++++++++++++++++ > src/backend/utils/fmgr/funcapi.c | 13 + > src/include/executor/executor.h | 1 + > src/include/executor/tableexpr.h | 69 ++++ > src/include/funcapi.h | 1 - > src/include/nodes/execnodes.h | 31 ++ > src/include/nodes/nodes.h | 4 + > src/include/nodes/parsenodes.h | 21 ++ > src/include/nodes/primnodes.h | 40 +++ > src/include/parser/kwlist.h | 3 + > src/include/parser/parse_coerce.h | 4 + > src/include/utils/xml.h | 2 + > src/include/utils/xpath_parser.h | 24 ++ > src/test/regress/expected/xml.out | 415 ++++++++++++++++++++++++ > src/test/regress/expected/xml_1.out | 323 +++++++++++++++++++ > src/test/regress/expected/xml_2.out | 414 ++++++++++++++++++++++++ > src/test/regress/sql/xml.sql | 170 ++++++++++ > 33 files changed, 4019 insertions(+), 64 deletions(-) > > -- > Álvaro Herrera https://www.2ndQuadrant.com/ > PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services >
