Good idea. I have applied the following patch to report in the error
message the string length and maximum, like we already do for long
words:
Old:
test=> select repeat('a', 3000)::tsvector;
ERROR: word is too long (3000 bytes, max 2046 bytes)
New:
test=> select repeat('a ', 3000000)::tsvector;
ERROR: string is too long for tsvector (1048576 bytes, max 1048575
bytes)
I did not backpatch this to 8.3 because it would require translation
string updates.
